+<h1>Building SDL with Borland's C++ compilers. </h1>
+      <b> by <a href="mailto:xevol@users.sourceforge.net"> David Snopek</a></b> 
+    and updated by <b><a href="mailto:Dominique@SavageSoftware.com.au">Dominique 
+  Louis</a></b> ( Last updated : 30th June 2003 ).<br>
+      <br>
+       These instructions cover how to compile SDL and its included test
+programs   using either  Borland <a href="#bcbwin">C++ Builder 5, 6 for Windows</a>, 
+ <a href="#k3">C++ Builder for Linux  ( AKA Kylix 3 )</a> or the free <a
+ href="#bccc">Borland C++ command-line compiler</a>. <br>
+            
+<h3> <b> Extract the files </b> </h3>
+            
+<p> Unzip the Borland.zip archive into <b>this</b> directory.  Do not unzip 
+  it into any  other directory because the makefiles ( *.mak ) and project 
+ files ( *.bpr ) use relative paths to refer to the SDL sources.  This  should 
+ create a directory named "Borland" inside of the top level SDL source directory. 
+   </p>
+            
+<h3> <b><a name="bcbwin"></a> Using Borland C++ Builder 5, 6 for Windows </b>
+</h3>
+            
+<p> Inside of the "Borland" directory there is a "bcb6" directory that contains 
+  a number  of Builder project files.  Double-click on the "libSDL.bpg" file 
+  icon.  Once Builder has  started click on the "<u>P</u>rojects" menu on 
+the  menu-bar and go down to  "B<u>u</u>ild All Projects" option.  <br>
+   This will proceed  to build SDL ( with Borland's calling convention ), 
+SDLmain,  and all  the <a href="#tests">test programs</a>. Currently, all 
+the <a href="#tests">test programs</a>  are dynamically linked to Sam Lantinga's 
+SDL.dll.</p>
+     
+<p><b>NOTE :</b> Borland's "lib" format and Microsoft's "lib" format are incompatible.
+&nbsp;<br>
+   If you wish to dynamically link to the SDL library supplied by Sam Lantinga 
+ in each release, I have created the correct *.libs for SDL 1.2.4 and they 
+ exist in the "/lib" directory.<br>
+   If you would like to create the *.lib files yourself, you will need to 
+make  use of Borland's "implib.exe" utility.<br>
+   </p>
+     
+<p><tt>IMPLIB</tt> works like this: </p>
+       
+<pre>    IMPLIB (destination lib name) (source dll)<br></pre>
+       
+<p> For example,</p>
+       
+<pre>    IMPLIB SDL.lib SDL.dll<br></pre>
+     
+<p>This assumes that SDL.dll was compiled with Visual C++ or similar.<br>
+   </p>
+     
+<p>To learn more about the difference between Borland's and Microsoft's *.lib 
+ format please read the article <a
+ href="http://www.bcbdev.com/articles/vcdll.htm">here</a>.<br>
+   </p>
+     
+<p>  <b><br>
+   NOTE :</b> The C++ Builder for Windows project format, is not compatible
+ with the Kylix  3 project format, hence the reason why they are in separate
+ directories.</p>
+            
+<h3> <b><a name="bccc"></a> Using the free Borland C++ command-line compiler 
+ </b> </h3>
+            
+<p> The free Borland compiler can be downloaded at no charge from <a
+ href="http://www.borland.com/bcppbuilder/freecompiler/"> the  Borland website 
+  </a>.  Make sure that it is installed and properly configured. </p>
+            
+<p> Open an MS-DOS Prompt.  Change to the "Borland\freebcc" directory under 
+  the  SDL source directory.  Type "make -f SDL.mak" to build SDL and "make 
+  -f  SDLmain.mak".  There are also makefiles for all of the <a
+ href="#tests">test  programs</a>, if you wish to build them. All .exes and 
+DLLs are created in the "test" SDL directory. Ify ou would like to create 
+the DLL and all the test applications, I have thrown together a basic batchfile 
+called "makeall.bat" which should create everything in the right order. </p>
+            
+<h3> <b> Output files </b> </h3>
+       No matter which compiler you used, three important files should have 
+ been  produced:        
+<ul>
+      	<li> SDL.dll ( Borland format ) </li>
+      	<li> SDL.lib&nbsp;( Borland format ) </li>
+      	<li> SDLmain.lib&nbsp;( Borland format ) </li>
+           
+</ul>
+       Both of the *.lib files will need to be added to all the projects
+that   use SDL and SDL.dll  must be placed some where the Windows dynamic
+linker   can find it (either in your  project directory or on the system
+path, C:\WINDOWS\SYSTEM).       
+<h3> <b><a name="k3"></a> Using Borland C++ Builder for Linux ( AKA Kylix 
+ 3 ) </b> </h3>
+              
+<p> Inside of the "Borland" directory there is a "k3" directory that contains 
+  a number  of Builder project files.  Double-click on the "libSDL.bpg" file 
+  icon.  Once Builder has  started click on the "<u>P</u>rojects" menu on 
+the  menu-bar and go down to  "B<u>u</u>ild All Projects" option.  This will 
+proceed  to build all  the <a href="#tests">test programs</a>.&nbsp;<br>
+   Linux  users do not need *.lib files as the Shared Object is linked right 
+ into the  project ( very neat actually, Windows should do this sort of thing 
+ as it is a lot easier for the developer ).  <br>
+      <b>NOTE :</b>&nbsp;The C++ Builder for Windows project format, is not
+ compatible with the Kylix  3 project format, hence the reason why they are
+ in separate directories.</p>
+           
+<p> On Mandrake 8.1 the shared objects for SDL are located in the /usr/lib 
+  directory as libSDL_*.so and the Mesa OpenGL shared objects are located 
+in  /usr/X11R6/lib as libGL*.so<br>
+       <br>
+       So if your setup is different you may need to change the project file
+  so that they re-link to the ones on your system.<br>
+       <br>
+       On Mandrake 8.1 the headers files are located at /usr/include/SDL/.
+ So  if you you have not installed the development RPMs ( usually named libSDL-devel*
+   ) for SDL ( not included ) you may have to change the include directory
+ within  some of the projects.<br>
+   </p>
+     
+<h3> Known Problems</h3>
+     The only known problem is that I ( Dominique Louis ), was unable to
+create  the projects that rebuilt the SDL shared objects under Linux, due
+to time  constraints and my lack of intimate knowledge of Linux.     
+<h3><a name="tests"><b> Test programs </b> </a></h3>
+   Some of the test programs require included media files ( *.wav; *.bmp
+etc   ). All the test programs are now created in the "test" directory, where
+the media files are ( usually ) so they should be ready to go.  <br>

+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.

+
+---
+http://www.libsdl.org/
+
+This is the Simple DirectMedia Layer, a general API that provides low
+level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
+and 2D framebuffer across multiple platforms.
+
+The current version supports Linux, Windows CE/95/98/ME/XP/Vista, BeOS,
+MacOS Classic, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX,
+and QNX.  The code contains support for Dreamcast, Atari, AIX, OSF/Tru64,
+RISC OS, SymbianOS, Nintendo DS, and OS/2, but these are not officially
+supported.
+
+SDL is written in C, but works with C++ natively, and has bindings to
+several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
+Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
+Pike, Pliant, Python, Ruby, and Smalltalk.
+
+This library is distributed under GNU LGPL version 2, which can be
+found in the file  "COPYING".  This license allows you to use SDL
+freely in commercial programs as long as you link with the dynamic
+library.
+
+The best way to learn how to use SDL is to check out the header files in
+the "include" subdirectory and the programs in the "test" subdirectory.
+The header files and test programs are well commented and always up to date.
+More documentation is available in HTML format in "docs/index.html", and
+a documentation wiki is available online at:
+	http://www.libsdl.org/cgi/docwiki.cgi
+
+The test programs in the "test" subdirectory are in the public domain.
+
+Frequently asked questions are answered online:
+	http://www.libsdl.org/faq.php
+
+If you need help with the library, or just want to discuss SDL related
+issues, you can join the developers mailing list:
+	http://www.libsdl.org/mailing-list.php
+
+Enjoy!

+SDL on BeOS R5
+==============
+
+You can build SDL on BeOS like any other GNU style package.
+e.g. ./configure && make && make install
+By default it is installed in /boot/develop/tools/gnupro/{bin,lib,etc.}
+
+Once you install SDL, you need to copy libSDL.so to /boot/home/config/lib,
+so it can be found by the dynamic linker.

+Using the Simple DirectMedia Layer with MacOS 7,8,9 on PPC
+==============================================================================
+
+These instructions are for people using the Apple MPW environment:
+http://developer.apple.com/tools/mpw-tools/
+
+CodeWarrior projects are available in the CWprojects directory.
+
+==============================================================================
+I.  Building the Simple DirectMedia Layer libraries:
+    (This step isn't necessary if you have the SDL binary distribution)
+
+  First, unpack the MPWmake.sea.hqx archive and move SDL.make into the
+  SDL directory.
+
+  Start MPW
+
+  Set the current directory within MPW to the SDL toplevel directory.
+
+  Build "SDL"  (Type Command-B and enter "SDL" in the dialog)
+
+  If everything compiles successfully, you now have the PPC libraries
+  "SDL" and "SDLmain.o" in the 'lib' subdirectory.
+
+==============================================================================
+II. Building the Simple DirectMedia Layer test programs:
+
+  First, unpack the MPWmake.sea.hqx archive, move the new rsrc directory to
+  the main SDL directory, and move the makefiles in the new test subdirectory
+  to the SDL 'test' subdirectory.
+
+  Start MPW
+
+  Set the current directory within MPW to the SDL 'test' subdirectory.
+
+  Build the programs that have an associated MPW makefile (file ending
+  with .make), including "testwin", "testalpha", and "graywin".
+
+  Copy the SDL library file into the test directory, and run!
+
+==============================================================================
+III. Building the Simple DirectMedia Layer demo programs:
+
+  Copy one of the test program Makefiles to the demo directory
+  and modify it to match the sources in the demo.
+
+==============================================================================
+IV.  Enjoy! :)
+
+  If you have a project you'd like me to know about, or want to ask questions,
+  go ahead and join the SDL developer's mailing list by sending e-mail to:
+
+	sdl-request@libsdl.org
+
+  and put "subscribe" into the subject of the message. Or alternatively you
+  can use the web interface:

+==============================================================================
+Using the Simple DirectMedia Layer with Mac OS X
+==============================================================================
+
+These instructions are for people using Apple's Mac OS X (pronounced
+"ten").
+
+From the developer's point of view, OS X is a sort of hybrid Mac and
+Unix system, and you have the option of using either traditional
+command line tools or Apple's IDE Xcode.
+
+To build SDL using the command line, use the standard configure and make
+process:
+
+	./configure
+	make
+	sudo make install
+
+You can also build SDL as a Universal library (a single binary for both
+PowerPC and Intel architectures), on Mac OS X 10.4 and newer, by using
+the fatbuild.sh script in build-scripts:
+	sh build-scripts/fatbuild.sh
+	sudo build-scripts/fatbuild.sh install
+This script builds SDL with 10.2 ABI compatibility on PowerPC and 10.4
+ABI compatibility on Intel architectures.  For best compatibility you
+should compile your application the same way.  A script which wraps
+gcc to make this easy is provided in test/gcc-fat.sh
+
+To use the library once it's built, you essential have two possibilities:
+use the traditional autoconf/automake/make method, or use Xcode.
+
+==============================================================================
+Using the Simple DirectMedia Layer with a traditional Makefile
+==============================================================================
+
+An existing autoconf/automake build system for your SDL app has good chances
+to work almost unchanged on OS X. However, to produce a "real" Mac OS X binary
+that you can distribute to users, you need to put the generated binary into a
+so called "bundle", which basically is a fancy folder with a name like
+"MyCoolGame.app".
+
+To get this build automatically, add something like the following rule to
+your Makefile.am:
+
+bundle_contents = APP_NAME.app/Contents
+APP_NAME_bundle: EXE_NAME
+	mkdir -p $(bundle_contents)/MacOS
+	mkdir -p $(bundle_contents)/Resources
+	echo "APPL????" > $(bundle_contents)/PkgInfo
+	$(INSTALL_PROGRAM) $< $(bundle_contents)/MacOS/
+
+You should replace EXE_NAME with the name of the executable. APP_NAME is what
+will be visible to the user in the Finder. Usually it will be the same
+as EXE_NAME but capitalized. E.g. if EXE_NAME is "testgame" then APP_NAME 
+usually is "TestGame". You might also want to use @PACKAGE@ to use the package
+name as specified in your configure.in file.
+
+If your project builds more than one application, you will have to do a bit
+more.  For each of your target applications, you need a seperate rule.
+
+If you want the created bundles to be installed, you may want to add this
+rule to your Makefile.am:
+
+install-exec-hook: APP_NAME_bundle
+	rm -rf $(DESTDIR)$(prefix)/Applications/APP_NAME.app
+	mkdir -p $(DESTDIR)$(prefix)/Applications/
+	cp -r $< /$(DESTDIR)$(prefix)Applications/
+
+This rule takes the Bundle created by the rule from step 3 and installs them
+into $(DESTDIR)$(prefix)/Applications/.
+
+Again, if you want to install multiple applications, you will have to augment
+the make rule accordingly.
+
+
+But beware! That is only part of the story! With the above, you end up with
+a bare bone .app bundle, which is double clickable from the Finder. But
+there are some  more things you should do before shipping yor product...
+
+1) The bundle right now probably is dynamically linked against SDL. That 
+   means that when you copy it to another computer, *it will not run*,
+   unless you also install SDL on that other computer. A good solution
+   for this dilemma is to static link against SDL. On OS X, you can
+   achieve that by linkinag against the libraries listed by
+     sdl-config --static-libs
+   instead of those listed by
+     sdl-config --libs
+   Depending on how exactly SDL is integrated into your build systems, the
+   way to achieve that varies, so I won't describe it here in detail
+2) Add an 'Info.plist' to your application. That is a special XML file which
+   contains some meta-information about your application (like some copyright
+   information, the version of your app, the name of an optional icon file,
+   and other things). Part of that information is displayed by the Finder
+   when you click on the .app, or if you look at the "Get Info" window.
+   More information about Info.plist files can be found on Apple's homepage.
+
+
+As a final remark, let me add that I use some of the techniques (and some
+variations of them) in Exult and ScummVM; both are available in source on
+the net, so feel free to take a peek at them for inspiration!
+
+
+==============================================================================
+Using the Simple DirectMedia Layer with Xcode
+==============================================================================
+
+These instructions are for using Apple's Xcode IDE to build SDL applications.
+
+- First steps
+
+The first thing to do is to unpack the Xcode.tar.gz archive in the
+top level SDL directory (where the Xcode.tar.gz archive resides).
+Because Stuffit Expander will unpack the archive into a subdirectory,
+you should unpack the archive manually from the command line:
+	cd [path_to_SDL_source]
+	tar zxf Xcode.tar.gz
+This will create a new folder called Xcode, which you can browse
+normally from the Finder.
+
+- Building the Framework
+
+The SDL Library is packaged as a framework bundle, an organized
+relocatable folder heirarchy of executible code, interface headers, 
+and additional resources. For practical purposes, you can think of a 
+framework as a more user and system-friendly shared library, whose library
+file behaves more or less like a standard UNIX shared library.
+
+To build the framework, simply open the framework project and build it. 
+By default, the framework bundle "SDL.framework" is installed in 
+/Library/Frameworks. Therefore, the testers and project stationary expect
+it to be located there. However, it will function the same in any of the
+following locations:
+
+    ~/Library/Frameworks
+    /Local/Library/Frameworks
+    /System/Library/Frameworks
+
+- Build Options
+    There are two "Build Styles" (See the "Targets" tab) for SDL.
+    "Deployment" should be used if you aren't tweaking the SDL library.
+    "Development" should be used to debug SDL apps or the library itself.
+
+- Building the Testers
+    Open the SDLTest project and build away!
+
+- Using the Project Stationary
+    Copy the stationary to the indicated folders to access it from
+    the "New Project" and "Add target" menus. What could be easier?
+
+- Setting up a new project by hand
+    Some of you won't want to use the Stationary so I'll give some tips:
+    * Create a new "Cocoa Application"
+    * Add src/main/macosx/SDLMain.m , .h and .nib to your project
+    * Remove "main.c" from your project
+    * Remove "MainMenu.nib" from your project
+    * Add "$(HOME)/Library/Frameworks/SDL.framework/Headers" to include path
+    * Add "$(HOME)/Library/Frameworks" to the frameworks search path
+    * Add "-framework SDL -framework Foundation -framework AppKit" to "OTHER_LDFLAGS"
+    * Set the "Main Nib File" under "Application Settings" to "SDLMain.nib"
+    * Add your files
+    * Clean and build
+
+- Building from command line
+    Use pbxbuild in the same directory as your .pbproj file
+         
+- Running your app
+    You can send command line args to your app by either invoking it from
+    the command line (in *.app/Contents/MacOS) or by entering them in the
+    "Executibles" panel of the target settings.
+    
+- Implementation Notes
+    Some things that may be of interest about how it all works...
+    * Working directory
+        As defined in the SDL_main.m file, the working directory of your SDL app
+        is by default set to its parent. You may wish to change this to better
+        suit your needs.
+    * You have a Cocoa App!
+        Your SDL app is essentially a Cocoa application. When your app
+        starts up and the libraries finish loading, a Cocoa procedure is called,
+        which sets up the working directory and calls your main() method.
+        You are free to modify your Cocoa app with generally no consequence 
+        to SDL. You cannot, however, easily change the SDL window itself.
+        Functionality may be added in the future to help this.

+Using the Simple DirectMedia Layer on Atari
+==============================================================================
+
+
+    If you want to build SDL from sources to create SDL programs on Atari:

+	
+    If you want to create SDL programs on Atari using SDL binary build,

+
+    If you want to configure a program using SDL on Atari,
+	    see sections IV - VI.
+
+
+==============================================================================
+I.  Building the Simple DirectMedia Layer libraries:
+    (This step isn't necessary if you have the SDL binary distribution)
+
+  Do the classic configure, with --disable-shared --enable-static and:
+
+    Tos version (should run everywhere):
+      --disable-threads
+    Tos does not support threads.
+
+    MiNT version (maybe Magic, only for multitasking OS):
+      --disable-pthreads --enable-pth
+    Mint and Magic may supports threads, so audio can be used with current
+    devices, like Sun audio, or disk-writing support. Like Tos, interrupt
+    audio without threads is more suited for Atari machines.
+
+  Then you can make ; make install it.

+xbios   MiNT    Uses MFP Timer A interrupt
+xbios   Magic   Uses MFP Timer A interrupt
+stfa    All     Uses MFP interrupt
+mcsn	TOS     Uses MFP Timer A interrupt
+mcsn    MiNT    Uses MiNT thread
+mcsn    Magic   Disabled
+gsxb    All     Uses GSXB callback
+
+Joypad driver always uses hardware access.
+OpenGL driver always uses OSMesa.
+
+(1) GEM does not report relative mouse motion, so xbios mouse driver is used
+to report this type event.
+A preliminary driver for /dev/mouse device driver is present, but is disabled
+till it can be used with other applications simultaneously.
+
+(2) If you build SDL with threads using the GNU pth library, timers are
+supported via the pth library.
+
+==============================================================================
+V.  Environment variables:
+
+SDL_VIDEODRIVER:
+	Set to 'xbios' to force xbios video driver
+	Set to 'gem' to force gem video driver
+
+SDL_VIDEO_GL_DRIVER:
+	Set to filename to load as OpenGL library, if you use SDL_GL_LoadLibrary()
+
+SDL_AUDIODRIVER:
+	Set to 'mint_gsxb' to force Atari GSXB audio driver
+	Set to 'mint_mcsn' to force Atari MCSN audio driver
+	Set to 'mint_stfa' to force Atari STFA audio driver
+	Set to 'mint_xbios' to force Atari Xbios audio driver
+	Set to 'mint_dma8' to force Atari 8 bits DMA audio driver
+	Set to 'audio' to force Sun /dev/audio audio driver
+	Set to 'disk' to force disk-writing audio driver
+
+SDL_ATARI_EVENTSDRIVER
+	Set to 'ikbd' to force IKBD 6301 keyboard driver
+	Set to 'gemdos' to force gemdos keyboard driver
+	Set to 'bios' to force bios keyboard driver
+
+SDL_JOYSTICK_ATARI:
+	Use any of these strings in the environment variable to enable or
+	disable a joystick:
+
+	'ikbd-joy1-[on|off]' for IKBD joystick on port 1 (hardware access)
+	'xbios-joy1-[on|off]' for IKBD joystick on port 1 (xbios access)
+	'porta-pad-[on|off]' for joypad and/or teamtap on port A
+	'porta-joy0-[on|off]' for joystick 0 on port A
+	'porta-joy1-[on|off]' for joystick 1 on port A
+	'porta-lp-[on|off]' for lightpen on port A
+	'porta-anpad-[on|off]' for analog paddle on port A
+	'portb-pad-[on|off]' for joypad and/or teamtap on port B
+	'portb-joy0-[on|off]' for joystick 0 on port B
+	'portb-joy1-[on|off]' for joystick 1 on port B
+	'portb-anpad-[on|off]' for analog paddle on port B
+
+	Default configuration is:
+		'ikbd-joy1-on' (if IKBD events driver enabled)
+		'xbios-joy1-on' (if gemdos/bios/gem events driver enabled)
+		'porta-pad-on portb-pad-on' (if available on the machine)
+
+	port[a|b]-[pad|joy?|lp|anpad]-* strings are mutually exclusives.
+	On such a port, you can only use a joypad OR 1 or 2 joysticks OR
+	a lightpen OR an analog paddle. You must disable joypad before
+	setting another controller.
+
+	The second joystick port on IKBD is used by the mouse, so not usable.
+	Another problem with the IKBD: mouse buttons and joystick fire buttons
+	are wired together at the hardware level, it means:
+		port 0                port 0           port 1
+		mouse left button  = joystick fire 0 = joystick fire 1
+		mouse right button = joystick fire 1 = joystick fire 0
+
+	Descriptions of joysticks/joypads:
+	- Joypads: 1 hat, 17 buttons (Atari Jaguar console-like).
+	- Joysticks: 1 hat, 1 button.
+	- Lightpen, analog paddles: 2 axis, 2 buttons. The 2 buttons are those
+	  affected to 1 button joysticks on the same port.
+
+==============================================================================
+VI.  More informations about drivers:
+
+OpenGL:
+	The default is to use the Mesa offscreen driver (osmesa.ldg). If you want
+	to use an older OpenGL implementation, like mesa_gl.ldg or tiny_gl.ldg,
+	your program must use SDL_GL_LoadLibrary() to do so, and retrieve the
+	needed function pointers with SDL_LoadFunction(). In all cases, the OpenGL
+	context is taken care of by SDL itself, you just have to use gl* functions.
+
+	However, there is one OpenGL call that has a different prototype in the old
+	implementations: glOrtho(). In the old implementations, it has 6 float as
+	parameters, in the standard one, it has 6 double parameters. If you want
+	to compile testdyngl, or any other SDL program that loads its OpenGL
+	library, you must change the glOrtho() prototype used in this program. In
+	osmesa.ldg, you can retrieve a glOrtho() with double parameters, by
+	searching for the function "glOrtho6d".
+
+Xbios video:
+	Video chip is detected using the _VDO cookie.
+	Screen enhancers are not supported, but could be if you know how to
+	use them.
+
+	ST, STE, Mega ST, Mega STE:
+		320x200x4 bits, shades of grey, available only for the purpose
+		of testing SDL.
+	TT:
+		320x480x8 and 320x240x8 (software double-lined mode).
+	Falcon:
+		All modes supported by the current monitor (RVB or VGA).
+		BlowUp and Centscreen extended modes, ScreenBlaster 3 current mode.
+	Milan:
+		Experimental support
+	Clones and any machine with monochrome monitor:
+		Not supported.
+
+Gem video:
+	Automatically used if xbios not available.
+
+	All machines:
+		Only the current resolution, if 8 bits or higher depth.
+
+IKBD keyboard, mouse and joystick driver:
+	Available if _MCH cookie is ST, Mega ST, STE, Mega STE, TT or Falcon.
+
+	Hades has an IKBD, but xbios is not available for video, so IKBD
+	driver is disabled.
+
+Gemdos and bios keyboard driver:
+	Available on all machines.
+
+Mouse and joystick xbios driver:
+	Available on all machines (I think).
+
+Joypad driver:
+	Available if _MCH cookie is STE or Falcon. Supports teamtap.
+
+PTH timer driver:
+	Available with multitasking OS.
+
+VBL timer driver:
+	Available on all machines (I think).
+
+Audio drivers:
+	Cookies _SND, MCSN, STFA and GSXB used to detect supported audio
+	capabilities.
+
+	STE, Mega STE, TT:
+		8 bits DMA (hardware access)
+		STFA, MCSN or GSXB driver if installed
+	Falcon:
+		8 bits DMA (hardware access)
+		Xbios functions

+  Patch version 0.9 of SDL(Simple DirectMedia Layer) for Nano-X API
+  =================================================================
+  
+  Authors: Hsieh-Fu Tsai, clare@setabox.com
+           Greg Haerr, greg@censoft.com
+
+  This patch is against SDL version 1.2.4.
+  It enhances previous patch 0.8 by providing direct framebuffer
+  access as well as dynamic hardware pixel type support, not
+  requiring a compile-time option setting for different framebuffer
+  modes.
+  Tested against Microwindows version 0.89pre9.
+
+  Older Microwindows versions
+  ===========================
+  If running on a version older than Microwindows 0.89pre9,
+  the following items might need to be patched in Microwindows.
+
+  1. Patch src/nanox/client.c::GrClose()
+  It fixes the client side GrClose(). In the original version, 
+  GrOpen() can only be called once. When the GrOpen() is called at 
+  the second time, the program will terminate. In order to prevent
+  this situation, we need to insert "nxSocket = -1" after 
+  "close(nxSocket)" in GrClose(). If you do not have this problem,
+  you may skip this step. 
+
+  2. Patch src/nanox/clientfb.c to return absolute x,y coordinates
+  when using GrGetWindowFBInfo().  Copy the version 0.89pre9
+  of src/nanox/clientfb.c to your system, or configure
+  using --disable-nanox-direct-fb.
+
+  =============
+  Quick Install 
+  =============
+
+  1. ./configure --disable-video-x11 --disable-video-fbcon \ 
+       --enable-video-nanox \ 
+       --with-nanox-pixel-type=[rgb/0888/888/565/555/332/pal] 
+  2. make clean 
+  3. make 
+  4. make install (as root) 
+
+  ============
+  Nitty-gritty 
+  ============
+
+  --enable-nanox-direct-fb       Use direct framebuffer access
+  --enable-nanox-debug           Show debug messages 
+  --enable-nanox-share-memory    Use shared-memory to speed up 
+
+  When running multi-threaded applications using SDL, such
+  as SMPEG, set THREADSAFE=Y in Microwindows' config file,
+  to enable GrXXX() system call critical section support.

+===========
+SDL on OS/2
+===========
+
+Last updated on May. 17, 2006.
+
+
+1. How to compile?
+------------------
+
+To compile this, you'll need the followings installed:
+- The OS/2 Developer's Toolkit
+- The OpenWatcom compiler 
+  (http://www.openwatcom.org)
+
+First of all, you have to unzip the Watcom-OS2.zip file. This will result in a 
+file called "makefile" and a file called "setvars.cmd" in this folder (and some
+more files...).
+
+Please edit the second, fourth and fifth lines of setvars.cmd file
+to set the folders where the toolkit, the OW compiler and the FSLib are. 
+You won't need NASM yet (The Netwide Assembler), you can leave that line.
+Run setvars.cmd, and you should get a shell in which you can
+compile SDL.
+
+Check the "makefile" file. There is a line in there which determines if the 
+resulting SDL.DLL will be a 'debug' or a 'release' build. The 'debug' version 
+is full of printf()'s, so if something goes wrong, its output can help a lot
+for debugging.
+
+Then run "wmake".
+This should create the SDL12.DLL and the corresponding SDL12.LIB file here.
+
+To test applications, it's a good idea to use the 'debug' build of SDL, and
+redirect the standard output and standard error output to files, to see what
+happens internally in SDL.
+(like: testsprite >stdout.txt 2>stderr.txt)
+
+To rebuild SDL, use the following commands in this folder:
+wmake clean
+wmake
+
+
+
+2. How to compile the testapps?
+-------------------------------
+
+Once you have SDL12.DLL compiled, navigate into the 'test' folder, copy in 
+there the newly built SDL12.DLL, and copy in there FSLib.DLL.
+
+Then run "wmake" in there to compile some of the testapps.
+
+
+
+3. What is missing?
+-------------------
+
+The following things are missing from this SDL implementation:
+- MMX, SSE and 3DNOW! optimized video blitters?
+- HW Video surfaces
+- OpenGL support
+
+
+
+4. Special Keys / Full-Screen support
+-------------------------------------
+
+There are two special hot-keys implemented:
+- Alt+Home switches between fullscreen and windowed mode
+- Alt+End simulates closing the window (can be used as a Panic key)
+Only the LEFT Alt key will work.
+
+
+
+5. Joysticks on SDL/2
+---------------------
+
+The Joystick detection only works for standard joysticks (2 buttons, 2 axes
+and the like). Therefore, if you use a non-standard joystick, you should
+specify its features in the SDL_OS2_JOYSTICK environment variable in a batch
+file or CONFIG.SYS, so SDL applications can provide full capability to your
+device. The syntax is:
+
+SET SDL_OS2_JOYSTICK=[JOYSTICK_NAME] [AXES] [BUTTONS] [HATS] [BALLS]
+
+So, it you have a Gravis GamePad with 4 axes, 2 buttons, 2 hats and 0 balls,
+the line should be:
+
+SET SDL_OS2_JOYSTICK=Gravis_GamePad 4 2 2 0
+
+If you want to add spaces in your joystick name, just surround it with
+quotes or double-quotes:
+
+SET SDL_OS2_JOYSTICK='Gravis GamePad' 4 2 2 0
+
+or
+
+SET SDL_OS2_JOYSTICK="Gravis GamePad" 4 2 2 0
+
+   Notive However that Balls and Hats are not supported under OS/2, and the
+value will be ignored... but it is wise to define these correctly because 
+in the future those can be supported.
+   Also the number of buttons is limited to 2 when using two joysticks,
+4 when using one joystick with 4 axes, 6 when using a joystick with 3 axes
+and 8 when using a joystick with 2 axes. Notice however these are limitations 
+of the Joystick Port hardware, not OS/2.
+
+
+
+6. Proportional windows
+-----------------------
+
+For some SDL applications it can be handy to have proportional windows, so
+the windows will keep their aspect ratio when resized.
+This can be achieved in two ways:
+
+- Before starting the given SDL application, set the
+  SDL_USE_PROPORTIONAL_WINDOW environment variable to something, e.g.:
+
+  SET SDL_USE_PROPORTIONAL_WINDOW=1
+  dosbox.exe
+
+- If you have a HOME environment variable set, then SDL will look for a file
+  in there called ".sdl.proportionals". If that file contains the name of the
+  currently running SDL executable, then that process will have proportional
+  windows automatically.
+
+  Please note that this file is created automatically with default values
+  at the first run.
+
+
+
+7. Audio in SDL applications
+----------------------------
+
+Audio effects are one of the most important features in games. Creating audio
+effects in sync with the game and without hickups and pauses in the audio are
+very important things.
+
+However there are multithreaded SDL applications that have tight loops as their
+main logic loop. This kills performance in OS/2, and takes too much CPU from
+other threads in the same process, for example from the thread to create the 
+sound effects.
+
+For this reason, the OS/2 port of SDL can be instructed to run the audio thread
+in high priority, which makes sure that there will be enough time for the 
+processing of the audio data.
+
+At default, SDL/2 runs the audio thread at ForegroundServer+0 priority. Well 
+written and well behaving SDL applications should work well in this mode.
+For other applications, you can tell SDL/2 to run the audio thread at 
+TimeCritical priority by setting an env.variable before starting the SDL app:
+
+    SET SDL_USE_TIMECRITICAL_AUDIO=1
+
+Please note that this is a bit risky, because if the SDL application runs a
+tight infinite loop in this thread, this will make the whole system 
+unresponsive, so use it with care, and only for applications that need it!
+
+
+
+8. Next steps...
+----------------
+
+Things to do:
+- Implement missing stuffs (look for 'TODO' string in source code!)
+- Finish video driver (the 'wincommon' can be a good example for missing
+  things like application icon and so on...)
+- Enable MMX/SSE/SSE2 acceleration functions
+- Rewrite CDROM support using DOS Ioctl for better support.

+ - Changed DLL name to include version info (currently SDL12.dll)
+
+Version 1.2 - 2006-05-01  - Doodle
+ - Modified makefile system to have only one makefile
+ - Included FSLib headers, DLL and LIB file
+
+Version 1.2 - 2006-02-26  - Doodle

+ - Added support for real unicode keycode conversion.
+
+Version 1.2.7 - 2006-01-20  - Doodle

+   )
+
+Version 1.2.7 - 2005-12-22  - Doodle

+   environment variable to something before starting the application
+   (e.g.: 
+    SET SDL_USE_PROPORTIONAL_WINDOW=1
+    dosbox.exe
+   )
+   or, if you have the HOME environment variable set, then SDL12.DLL will
+   create a file in that directory called .sdl.proportionals, and you can
+   put there the name of executable files that will be automatically made
+   proportional.
+
+Version 1.2.7 - 2005-10-14  - Doodle
+ - Enabled Exception handler code in FSLib to be able to restore original
+   desktop video mode in case the application crashes.
+ - Added the missing FSLib_Uninitialize() call into SDL.

+ - Small fixes for DosBox incorporated into public release
+ - Fixed semaphore support (SDL_syssem.c)
+ - Fixed FSLib to have good clipping in scaled window mode,
+   and to prevent occasional desktop freezes.
+
+Version 1.2.7 - 2004-09-08a - Caetano
+	- Improved joystick support (general verifications about hardware).
+	- Added support up to 8 buttons in 2 axes joysticks and 6 buttons in 3 axes joysticks.
+	- Added support to environment variable SDL_OS2_JOYSTICK to specify a joystick.
+	- Improved Joystick test to handle every type of joystick and display only relevant information.
+	- Merged with Doodle 2004-09-08
+	- Little tid up in README.OS2
+	- Added explanation about SDL_OS2_JOYSTICK environment variable on README.OS2
+
+Version 1.2.7 - 2004-09-07 - Caetano
+	- Merged with changes in headers for GCC compiling.
+	- Added Joystick support using basic IBM GAME$ support, allowing it to work with all joystick drivers since OS/2 2.1.
+	- Improved joystick detection (hacked!). OS/2 do not allow real joystick detection, so... 
+	- Modified makefile in test to compile "testjoystick". Anyway, it's useless, since it seems to cause a lot of trouble in OS/2 (because os video routines, not Joystick support).
+	- Created separated Joystick test program to test only joystick functions.
+	- Improved joystick auto-centering.
+	- Improved the coordinate correction routine to use two scale factors for each axis.
+
+Version 1.2.7 - 2004-07-05 - Caetano
+	- Corrected the time returned by status in CDROM support (it was incorrect)
+	- Added the testcdrom.c and corrected the linking directive (it was causing an error)
+
+Version 1.2.7 - 2004-07-02a - Caetano
+	- Corrected a little problem in a comment at SDL-1.2.7\test\torturethread.c, line 18 (missing */, nested comment)
+	- Added CDROM support to tree (SDL-1.2.7\src\cdrom\os2\SDL_syscdrom.c)
+	- Modified makefile (SDL-1.2.7\src\makefiles.wat and SDL-1.2.7\watcom.mif) to build with CDROM support
+	- Added the "extra" SDL_types.h forgotten in 2004-07-02 version.

+ ========================
+  Using SDL with PicoGUI
+ ========================
+
+- Originally contributed by Micah Dowty <micahjd@users.sourceforge.net>
+
+PicoGUI is a scalable GUI system with a unique architecture, primarily focused
+on scalability to various embedded systems. You can find more information
+including a FAQ at http://picogui.org
+
+To use the patch:
+
+  1. When compiling, add the "--enable-video-picogui" switch to ./configure
+
+  2. When running your program, ensure that the picogui driver for SDL
+     is in use by setting the SDL_VIDEODRIVER environment variable 
+     to "picogui".
+
+  3. The program must also be linked to the C client library for PicoGUI
+     (libpgui.so). If the program is being compiled with a patched SDL 
+     installed this should be done automatically. If you want to use an
+     existing binary with PicoGUI, you can set the LD_PRELOAD environment
+     variable to the path of your libpgui.so file.
+
+Capabilities:
+
+  So far only basic functionality is provided on true color (linear16/24/32)
+  devices. Accessing a memory mapped bitmap, updating the display, and handling
+  mouse/keyboard input. This functionality has been tested with several
+  applications, including mplayer, Xine, sldroids, and Abuse.
+
+TODO list:
+
+  - YUV overlays will be helpful for watching video on set top boxes or other
+    embedded devices that have some graphics acceleration hardware
+
+  - Account for rotated bitmap storage in pgserver
+
+  - Support for hiding or changing the cursor
+
+  - The display should be centered when the SDL application is smaller
+    than the PicoGUI panel
+
+  - Fullscreen or any other special modes
+
+  - Support for indexed and grayscale modes
+
+  - Probably much more...

+
+* Porting To A New Platform
+
+  The first thing you have to do when porting to a new platform, is look at
+include/SDL_platform.h and create an entry there for your operating system.
+The standard format is __PLATFORM__, where PLATFORM is the name of the OS.
+Ideally SDL_platform.h will be able to auto-detect the system it's building
+on based on C preprocessor symbols.
+
+There are two basic ways of building SDL at the moment:
+
+1. The "UNIX" way:  ./configure; make; make install
+
+   If you have a GNUish system, then you might try this.  Edit configure.in,
+   take a look at the large section labelled:
+	"Set up the configuration based on the target platform!"
+   Add a section for your platform, and then re-run autogen.sh and build!
+
+2. Using an IDE:
+
+   If you're using an IDE or other non-configure build system, you'll probably
+   want to create a custom SDL_config.h for your platform.  Edit SDL_config.h,
+   add a section for your platform, and create a custom SDL_config_{platform}.h,
+   based on SDL_config.h.minimal and SDL_config.h.in
+
+   Add the top level include directory to the header search path, and then add
+   the following sources to the project:
+	src/*.c
+	src/audio/*.c
+	src/cdrom/*.c
+	src/cpuinfo/*.c
+	src/events/*.c
+	src/file/*.c
+	src/joystick/*.c
+	src/stdlib/*.c
+	src/thread/*.c
+	src/timer/*.c
+	src/video/*.c
+	src/audio/disk/*.c
+	src/video/dummy/*.c
+	src/joystick/dummy/*.c
+	src/cdrom/dummy/*.c
+	src/thread/generic/*.c
+	src/timer/dummy/*.c
+	src/loadso/dummy/*.c
+
+
+Once you have a working library without any drivers, you can go back to each
+of the major subsystems and start implementing drivers for your platform.
+
+If you have any questions, don't hesitate to ask on the SDL mailing list:
+	http://www.libsdl.org/mailing-list.php

+Enjoy!

+Last changed at 24 Apr 2004.
+
+======================================================================
+Table of Contents:
+
+1. OpenGL.
+2. Wheel and multi-button mouses.
+3. CDROM handling issues.
+4. Hardware video overlays.
+5. Shared library building.
+6. Some building issues.
+7. Environment variables.
+
+======================================================================
+1. OpenGL:
+
+    OpenGL works well and is stable, but fullscreen mode has not  been
+heavily tested yet.
+    If you have QNX RtP version 6.1.0 or above you must  download  the
+Photon3D runtime from http://developers.qnx.com or install it from the
+public repository or from the public CD, available with QNX. OS versi-
+ons below 6.1.0 are not supported.
+    When creating an OpenGL context, software renderer mode is artifi-
+cially selected (QSSL made acceleration  only  for  Voodoo  boards  in
+fullscreen mode, sorry but I don't have this board  to  test  OpenGL -
+maybe it works or maybe not :)). If you  want  acceleration - you  can
+remove one line in the source code: find the  file SDL_ph_image.c  and
+remove the following
+
+    OGLAttrib[OGLargc++]=PHOGL_ATTRIB_FORCE_SW;
+     
+line in the ph_SetupOpenGLContext() function or change the argument to
+PHOGL_ATTRIB_FORCE_HW or PHOGL_ATTRIB_FAVOR_HW.
+
+======================================================================
+2. Wheel and multi-button mouses:
+
+    Photon emits  keyboard  events (key up and  down)  when the  mouse
+wheel is moved. The key_scan field appears valid, and it contains zero.
+That is a basic method of detecting  mouse  wheel events under Photon.
+It looks like a hack, but it  works for me :) on various PC configura-
+tions.
+
+I've tested it on:
+
+1. Genius Optical NetScroll/+ PS/2 (1 wheel)
+2. A4Tech Optical GreatEye WheelMouse PS/2,  model: WOP-35.  (2 wheels
+   + 2 additional buttons). The wheel for vertical scrolling  works as
+   usual, but the second wheel for horizontal scrolling emits  two se-
+   quential events up or down, so it can provide faster scrolling than
+   the first wheel. Additional buttons don't emit  any  events, but it
+   looks like they're handled by photon in an unusual way - like click
+   to front, but works not with any window, looks like a fun bug-o-fe-
+   ature :).
+
+======================================================================
+3. CDROM handling issues:
+
+    Access to CDROM can only be  provided  with  'root'  privileges. I
+can't do anything about that, /dev/cd0 has brw------- permissions  and
+root:root rights.
+
+======================================================================
+4. Hardware video overlays:
+
+    Overlays can flicker  during  window  movement,  resizing, etc. It
+happens because the photon driver updates the real window contents be-
+hind the overlay, then draws the temporary chroma key color  over  the
+window contents. It can be done without using the chroma key but  that
+causes the overlay to always be on top. So  flickering  during  window
+movement is preferred instead.
+    Double buffering code is temporarily disabled in the photon driver
+code, because on my GF2-MX it can accidentally cause a buffer  switch,
+which causes the old frame to show. S3 Savage4 has the  same  problem,
+but ATI Rage 128 doesn't. I think it can be fixed later. Current  code
+works very well, so maybe double buffering is not needed right now.
+    Something strange happens when you try to move the window with the
+overlay beyond the left border  of the screen. The  overlay  tries  to
+stay at position x=0, but when attempting to move it  a  bit  more  it
+jumps to position x=-60 (on GF2-MX, on ATI Rage128 this  value  a  bit
+smaller). It's really strange, looks  like  the  overlay  doesn't like
+negative coordinates.
+
+=======================================================================
+5. Shared library building:
+
+    A shared library can be built, but before running  the  autogen.sh
+script you must manually delete the libtool.m4 stuff from the acinclu-
+de.m4 file (it comes after the ESD detection code up to the end of the
+file), because the libtool stuff in the acinclude.m4 file was very old
+in SDL distribution before the version 1.2.7 and doesn't knew anything
+about QNX. SDL 1.2.7 distribution contains the  new libtool.m4 script,
+but anyway  it  is  broken :), Just  remove  it, then  run "libtoolize
+--force --copy",  delete the file aclocal.m4 if it is exists and after
+that run the  autogen.sh script. SDL 1.2.8 contains  fixed libtool.m4,
+ltmain.sh and config.sub files, so you  can  just  run  the autogen.sh
+script.
+
+======================================================================
+6. Some building issues:
+
+    Feel free to not use the --disable-shared configure option if you'
+ve read the above comment about 'Shared  library  building'. Otherwise
+this  option  is  strongly  recommended, as  without it the sdl-config
+script will be broken.
+
+    Run the configure script without x11 support, e.g.:
+
+    a) for OpenGL support:
+    ./configure --prefix=/usr           \
+                --disable-video-x11     \
+                --disable-shared
+
+    b) without OpenGL support:
+    ./configure --prefix=/usr           \
+                --disable-video-x11     \
+                --disable-shared        \
+                --disable-video-opengl
+
+    And of course dont forget to specify --disable-debug, which  is on
+by default, to disable debug and enable the expensive optimizations.
+
+    In the test directory also run the ./configure script without
+x11 support, e.g.:
+
+    ./configure  --with-sdl-prefix=/usr            \
+                 --with-sdl-exec-prefix=/usr       \
+                 --prefix=/usr --without-x
+
+======================================================================
+7. Environment variables:
+
+    Please note that the photon driver  is  sensible to the  following
+environmental variables:
+
+ * SDL_PHOTON_FULLSCREEN_REFRESH - this environment variable  controls
+the refresh  rate  in  all  fullscreen  modes. Be  carefull !!! Photon
+drivers usually do not checking the maximum  refresh rate, which video
+adapter or monitor supports.
+
+ * SDL_VIDEO_WINDOW_POS - can be  set in the "X,Y" format.  If X and Y
+coordinates are bigger than the current desktop resolution, then  win-
+dow positioning across  virtual  consoles is activated. If X and Y are
+smaller than the desktop resolution  then  window  positioning  in the
+current console is activated. The word "center" can be used instead of
+coordinates, it  produces  the  same  behavior  as  SDL_VIDEO_CENTERED
+environmental variable.
+
+ * SDL_VIDEO_CENTERED - if this environmental variable exists then the
+window centering is perfomed in the current virtual console.
+
+Notes: The SDL_VIDEO_CENTERED enviromental  variable  has greater pri-
+ority than the SDL_VIDEO_WINDOW_POS in case if both variables are sup-
+plied to the application.

+  One thing to note is that the above configure will include joystick

+  reason for this is to avoid link / compile / runtime errors with
+  applications that have joystick support.

+
+  After installing, making sure the correct sdl-config is in your
+  path, run configure like this:

+
+==============================================================================
+IV.  Application porting notes
+
+  One thing I have noticed is that applications sometimes don't exit
+  correctly. Their icon remains in the taskbar and they tend to
+  relaunch themselves automatically. I believe this problem doesn't
+  occur if you exit your application using the exit() method. However,
+  if you end main() with 'return 0;' or so, this seems to happen.
+
+  Also note that when running in landscape mode - i.e requesting a
+  window that is HEIGHT pixels wide and WIDTH pixels high, where WIDTH
+  and HEIGHT normally is 240 and 320 - the image is blitted so that
+  the hardware buttons are on the left side of the display. This might
+  not always be desirable but such is the code today.
+
+
+==============================================================================
+V.  Enjoy! :)
+
+  If you have a project you'd like me to know about, or want to ask questions,
+  go ahead and join the SDL developer's mailing list by sending e-mail to:
+
+	sdl-request@libsdl.org
+
+  and put "subscribe" into the subject of the message. Or alternatively you
+  can use the web interface:
+
+	http://www.libsdl.org/mailman/listinfo/sdl
+  
+==============================================================================
+VI.  What is supported:
+
+Keyboard (Sharp Zaurus)
+Hardware buttons
+Stylus input (mouse)
+Video. Allows fullscreen both in portrait mode (up to WIDTHxHEIGHT
+size window) and in landscape mode (up to HEIGHTxWIDTH). 
+
+All other SDL functionality works like a normal Linux system (threads,
+audio etc).

+Readme for RISC OS port of SDL
+==============================
+
+This document last updated on 2nd Februrary 2006
+
+This is a RISC OS port of the Simple Direct Media Layer (SDL) by Alan Buckley with contributions from Peter Naulls.
+
+Details of the SDL can be found at http://www.libsdl.org.
+
+The source code including the RISC OS version can be obtained from:
+
+http://www.libsdl.org.
+
+Pre built libraries and many games and applications compiled for RISC OS using this library can be downloaded from The Unix Porting Project at http://www.riscos.info/unix/.
+
+This is released under the LGPL see the file COPYING for details.
+
+
+Compiling applications under RISC OS
+====================================
+
+Add -ISDL: for the C compiler flags if you include the files in the SDL directory. e.g. #include "SDL/SDL.h"
+Add -ISDL:SDL for the C compiler flags if you include the files directly. e.g. #include "SDL/SDL.h"
+
+Add -LSDL: -lSDL to the link stage of compilation.
+
+For example, to compile the testbitmap.c sample you could use:
+
+gcc -ISDL:SDL -LSDL: -lSDL testbitmap.c -otestbitmap
+
+
+RISC OS port of SDL runtime information
+=======================================
+
+Runtime requirements
+--------------------
+
+This library currently needs a minimum of RISC OS 3.6. The source code for the library (and a lot of the programs built with it) also need long file names.
+
+To use the audio you also need 16 bit sound and to have installed the DigitalRender module by Andreas Dehmel version 0.51 available from his
+web site: http://home.t-online.de/~zarquon
+This is loaded when needed by UnixLib.
+
+Note: As most programs ported from other OSes use high resolution graphics and a memory back buffer a machine with a StrongARM processor and 1 or 2MB of VRAM (or a better machine) is recomended.
+
+
+RISC OS runtime parameters
+--------------------------
+
+Several environmental variables have been defined to make porting programs easier (i.e. By setting these variable you do not need to have source code differences between OSes).
+
+They are all defined on an application basis.
+
+The <appname> used below is found as follows:
+1. Use the name of the program unless it is !RunImage
+2. Check the folder specification for the folder !RunImage is run from. If it is a folder name use that name, otherwise if it is an environmental variable of the form <XXX$Dir> use the value of XXX.
+
+The variables are:
+
+SDL$<appname>$TaskName
+
+The name of the task for RISC OS. If omitted then <appname> is used for the task name,
+
+SDL$<appname>$BackBuffer
+
+Set to 1 to use a system memory back buffer for the screen in full screen mode. Some programs on other systems assume their is always a back buffer even though the SDL specification specifies this is not the case. The current RISC OS implementation uses direct writes to the screen if a hardware fullscreen is requested.
+
+Set to 2 to use an ARM code full word copy. This is faster than the standard back buffer, but uses aligned words only so it is possible (but unlikely) for it to corrupt the screen for 8bpp and 16bpp modes.
+
+Set to 3 to use a RISC OS sprite as the back buffer. This is usually the slowest for most SDL applications, however it may be useful in the future as Sprite acceleration is added to various hardware that runs RISC OS.
+
+SDL$<appname>$CloseAction - set the action for the close icon. Again as programs don't match the specification you can set this to 0 to remove the close icon from the main window for applications where this does not affect the program.
+
+
+RISC OS SDL port API notes
+==========================
+
+Current level of implementation
+-------------------------------
+
+The following list is an overview of how much of the SDL is implemented. The areas match the main areas of the SDL.
+
+video - Mostly done. Doesn't cover gamma, YUV-overlay or OpenGL.
+Window Manager - Mostly done. SetIcon/IconifyWindow not implemented.
+Events - Mostly done. Resize and some joystick events missing.
+Joystick - Currently assumes a single joystick with 4 buttons.
+Audio - Done
+CDROM - Not implemented.
+Threads - Done
+Timers - Done
+
+Thread support can be removed by defining DISABLE_THREADS and recompiling the library.
+
+SDL API notes
+-------------
+
+This section contains additional notes on some specific commands.
+
+SDL_SetVideoMode
+  On RISC OS a fullscreen mode directly accesses the screen. This can be modified by the environmental variable (SDL$<appname>$BackBuffer) or by using the SDL_SWSURFACE flag to write to an offscreen buffer that is updated using SDL_UpdateRects.
+  Open GL is not supported so SDL_OPENGL and SDL_OPENGLBLIT flags fail.
+  SDL_RESIZEABLE and SDL_NOFRAME flags are not supported.
+
+SDL_SetColors
+  In a wimp mode the screen colours are not changed for a hardware palette instead the RISC OS sprite colour mapping is used to get the best matching colours.
+
+SDL_CreateCursor
+   Inverted colour is not supported.
+
+SDL_WM_ToggleFullScreen
+   Currently this won't work if the application starts up in Fullscreen mode.
+   Toggling to fullscreen will only work if the monitor is set up to support the exact screen size requested.
+
+SDL_EnableUNICODE
+   Unicode translation used here is only really accurate for 7 bit characters.
+
+SDL_NumJoysticks/JoystickName etc.
+   Hardcoded to expect only 1 joystick with 4 buttons if the Joystick module is loaded.
+
+SDL_GetTicks
+   Timer used has only a centisecond accuracy. This applies to other time related functions.
+   
+SDL_Delay
+   Modified to poll keyboard/mouse during the delay on the event thread.
+
+
+Notes on current implementation
+-------------------------------
+
+Keyboard and mouse are polled so if too long a time is spent between a call to SDL_PumpEvents, functions that use it, or SDL_Delay events can be missed.

+
+Using SDL under Windows with the OpenWatcom compiler
+====================================================
+
+Prerequisites
+-------------
+
+I have done the port under Windows XP Home with SP2 installed. Windows
+2000 should also be working. I'm not so sure about ancient Windows NT,
+since only DirectX 3 is available there. Building should be possible,
+but running the compiled applications will probalbly fail with
+SDL_VIDEODRIVER=directx. The windib driver should work, though.
+
+To compile and use the SDL with Open Watcom you will need the following:
+- Open Watcom compiler. I used version 1.5. The environment variables
+  PATH, WATCOM and INCLUDE need to be set appropriately - please consult
+  the OpenWatcom documentation and instructions given during the
+  installation of the compiler.
+  My setup looks like this in owvars.bat:
+    set WATCOM=C:\watcom
+    set INCLUDE=%WATCOM%\h;%WATCOM%\h\nt
+    set PATH=%PATH%;%WATCOM%\binnt;%WATCOM%\binw
+- A fairly recent DirectX SDK. The original unmodified DX8 SDK works, as
+  well as the minimal DirectX 7 SDK from the Allegro download site
+  (<http://alleg.sourceforge.net/files/dx70_min.zip>).
+- The SDL sources from Subversion
+- The file Watcom-Win32.zip (now available in Subversion)
+
+
+Building the Library
+--------------------
+
+1) In the SDL base directory extract the archive Watcom-Win32.zip. This
+   creates a subdirectory named 'watcom'.
+2) The makefile expects the environment variable DXDIR to be set to the
+   base directory of a DirectX SDK. I have tried a stock DX8 SDK from
+   Microsoft as well as the minimal DirectX 7 SDK from the Allegro
+   download site.
+   You can also edit the makefile directly and hard code your path to
+   the SDK on your system.
+   I have this in my setup:
+     set DXDIR=D:\devel\DX8_SDK
+3) Enter the watcom directory and run
+     wmake sdl
+4) All tests from the test directory are working and can be built by
+   running
+     wmake tests
+
+Notes:
+
+ The makefile offers some options to tweak the way the library is built.
+ You have at your disposal the option to build a static (default)
+ library, or a DLL (with tgt=dll). You can also choose whether to build
+ a Release (default) or a Debug version (with build=debug) of the tests
+ and library. Please consult the usage comment at the top of the
+ makefile for usage instructions.
+
+ If you specify a test target (i.e. 'wmake tests' for all tests, or
+ selected targets like 'wmake testgl testvidinfo testoverlay2'), the
+ tests are always freshly compiled and linked. This is done to
+ minimise hassle when switching between library versions (static vs.
+ DLL), because they require subtly different options.
+ Also, the test executables are put directly into the test directory,
+ so they can find their data files. The clean target of the makefile
+ removes the test executables and the SDL.dll file from the test
+ directory.
+
+ To use the library in your own projects with Open Watcom, you can use
+ the way the tests are built as base of your own build environment.
+
+ The library can also be built with the stack calling convention of the
+ compiler (-6s instead of -6r).
+
+
+Test applications

+I've tried to make all tests work. The following table gives an overview

+==============================================================================
+Using the Simple DirectMedia Layer with OpenBSD/wscons
+==============================================================================
+
+The wscons SDL driver can be used to run SDL programs on OpenBSD
+without running X.  So far, the driver only runs on the Sharp Zaurus,
+but the driver is written to be easily extended for other machines.
+The main missing pieces are blitting routines for anything but 16 bit
+displays, and keycode maps for other keyboards.  Also, there is no
+support for hardware palettes.
+
+There is currently no mouse support.
+
+To compile SDL with support for wscons, use the
+"--enable-video-wscons" option when running configure.  I used the
+following command line:
+
+./configure --disable-oss --disable-ltdl --enable-pthread-sem \
+	    --disable-esd --disable-arts --disable-video-aalib  \
+	    --enable-openbsdaudio --enable-video-wscons \
+	    --prefix=/usr/local --sysconfdir=/etc
+
+
+Setting the console device to use
+=================================
+
+When starting an SDL program on a wscons console, the driver uses the
+current virtual terminal (usually /dev/ttyC0).  To force the driver to
+use a specific terminal device, set the environment variable
+SDL_WSCONSDEV:
+
+bash$ SDL_WSCONSDEV=/dev/ttyC1 ./some-sdl-program
+
+This is especially useful when starting an SDL program from a remote
+login prompt (which is great for development).  If you do this, and
+want to use keyboard input, you should avoid having some other program
+reading from the used virtual console (i.e., do not have a getty
+running).
+
+
+Rotating the display
+====================
+
+The display can be rotated by the wscons SDL driver.  This is useful
+for the Sharp Zaurus, since the display hardware is wired so that it
+is correctly rotated only when the display is folded into "PDA mode."
+When using the Zaurus in "normal," or "keyboard" mode, the hardware
+screen is rotated 90 degrees anti-clockwise.
+
+To let the wscons SDL driver rotate the screen, set the environment
+variable SDL_VIDEO_WSCONS_ROTATION to "CW", "CCW", or "UD", for
+clockwise, counter clockwise, and upside-down rotation respectively.
+"CW" makes the screen appear correct on a Sharp Zaurus SL-C3100.
+
+When using rotation in the driver, a "shadow" frame buffer is used to
+hold the intermediary display, before blitting it to the actual
+hardware frame buffer.  This slows down performance a bit.
+
+For completeness, the rotation "NONE" can be specified to use a shadow
+frame buffer without actually rotating.  Unsetting
+SDL_VIDEO_WSCONS_ROTATION, or setting it to '' turns off the shadow
+frame buffer for maximum performance.
+
+
+Running MAME
+============
+
+Since my main motivation for writing the driver was playing MAME on
+the Zaurus, I'll give a few hints:
+
+XMame compiles just fine under OpenBSD.
+
+I'm not sure this is strictly necessary, but set
+
+MY_CPU = arm
+
+in makefile.unix, and
+
+CFLAGS.arm = -DLSB_FIRST -DALIGN_INTS -DALIGN_SHORTS
+
+in src/unix/unix.max
+
+to be sure.
+
+The latest XMame (0.101 at this writing) is a very large program.
+Either tinker with the make files to compile a version without support
+for all drivers, or, get an older version of XMame.  My recommendation
+would be 0.37b16.
+
+When running MAME, DO NOT SET SDL_VIDEO_WSCONS_ROTATION!  Performace
+is MUCH better without this, and it is COMPLETELY UNNECESSARY, since
+MAME can rotate the picture itself while drawing, and does so MUCH
+FASTER.
+
+Use the Xmame command line option "-ror" to rotate the picture to the
+right.
+
+
+Acknowledgments
+===============
+
+I studied the wsfb driver for XFree86/Xorg quite a bit before writing
+this, so there ought to be some similarities.

+
+This is a list of API changes in SDL's version history.
+
+Version 1.0:
+
+1.2.14:
+	Added cast macros for correct usage with C++:
+		SDL_reinterpret_cast(type, expression)
+		SDL_static_cast(type, expression)
+
+	Added SDL_VIDEO_FULLSCREEN_DISPLAY as a preferred synonym for 
+	SDL_VIDEO_FULLSCREEN_HEAD on X11.
+
+	Added SDL_DISABLE_LOCK_KEYS environment variable to enable normal
+	up/down events for Caps-Lock and Num-Lock keys.
+
+1.2.13:
+	Added SDL_BUTTON_X1 and SDL_BUTTON_X2 constants.
+
+1.2.12:
+	Added SDL_VIDEO_ALLOW_SCREENSAVER to override SDL's disabling
+	of the screensaver on Mac OS X and X11.
+
+1.2.10:
+	If SDL_OpenAudio() is passed zero for the desired format
+	fields, the following environment variables will be used
+	to fill them in:
+		SDL_AUDIO_FREQUENCY
+		SDL_AUDIO_FORMAT
+		SDL_AUDIO_CHANNELS
+		SDL_AUDIO_SAMPLES
+	If an environment variable is not specified, it will be set
+	to a reasonable default value.
+
+	Added support for the SDL_VIDEO_FULLSCREEN_HEAD environment
+	variable, currently supported on X11 Xinerama configurations.
+
+	Added SDL_GL_SWAP_CONTROL to wait for vsync in OpenGL applications.
+
+	Added SDL_GL_ACCELERATED_VISUAL to guarantee hardware acceleration.
+
+	Added current_w and current_h to the SDL_VideoInfo structure,
+	which is set to the desktop resolution during video intialization,
+	and then set to the current resolution when a video mode is set.
+
+	SDL_SetVideoMode() now accepts 0 for width or height and will use
+	the current video mode (or the desktop mode if no mode has been set.)
+
+	Added SDL_GetKeyRepeat()
+
+	Added SDL_config.h, with defaults for various build environments.
+
+1.2.7:
+	Added CPU feature detection functions to SDL_cpuinfo.h:
+		SDL_HasRDTSC(), SDL_HasMMX(), SDL_Has3DNow(), SDL_HasSSE(),
+		SDL_HasAltiVec()
+	Added function to create RWops from const memory: SDL_RWFromConstMem()
+
+1.2.6:
+	Added SDL_LoadObject(), SDL_LoadFunction(), and SDL_UnloadObject()
+
+	Added SDL_GL_MULTISAMPLEBUFFERS and SDL_GL_MULTISAMPLESAMPLES for FSAA
+
+1.2.5:
+	Added SDL_BUTTON_WHEELUP (4) and SDL_BUTTON_WHEELDOWN (5)
+
+	Added SDL_GL_STEREO for stereoscopic OpenGL contexts
+
+1.2.0:
+	Added SDL_VIDEOEXPOSE event to signal that the screen needs to
+	be redrawn.  This is currently only delivered to OpenGL windows
+	on X11, though it may be delivered in the future when the video
+	memory is lost under DirectX.
+
+1.1.8:
+	You can pass SDL_NOFRAME to SDL_VideoMode() to create a window
+	that has no title bar or frame decoration.  Fullscreen video
+	modes automatically have this flag set.
+
+	Added a function to query the clipping rectangle for a surface:
+		void SDL_GetClipRect(SDL_Surface *surface, SDL_Rect *rect)
+
+	Added a function to query the current event filter:
+		SDL_EventFilter SDL_GetEventFilter(void)
+
+	If you pass -1 to SDL_ShowCursor(), it won't change the current
+	cursor visibility state, but will still return it.
+
+	SDL_LockSurface() and SDL_UnlockSurface() are recursive, meaning
+	you can nest them as deep as you want, as long as each lock call
+	has a matching unlock call.  The surface remains locked until the
+	last matching unlock call.
+
+	Note that you may not blit to or from a locked surface.
+
+1.1.7:
+	The SDL_SetGammaRamp() and SDL_GetGammaRamp() functions now take
+	arrays of Uint16 values instead of Uint8 values.  For the most part,
+	you can just take your old values and shift them up 8 bits to get
+	new correct values for your gamma ramps.
+
+	You can pass SDL_RLEACCEL in flags passed to SDL_ConvertSurface()
+        and SDL will try to RLE accelerate colorkey and alpha blits in the
+	resulting surface.
+
+1.1.6:
+	Added a function to return the thread ID of a specific thread:
+		Uint32 SDL_GetThreadID(SDL_Thread *thread)
+	If 'thread' is NULL, this function returns the id for this thread.
+
+1.1.5:
+	The YUV overlay structure has been changed to use an array of
+	pitches and pixels representing the planes of a YUV image, to
+	better enable hardware acceleration.  The YV12 and IYUV formats
+	each have three planes, corresponding to the Y, U, and V portions
+	of the image, while packed pixel YUV formats just have one plane.
+
+	For palettized mode (8bpp), the screen colormap is now split in
+	a physical and a logical palette. The physical palette determines
+	what colours the screen pixels will get when displayed, and the
+	logical palette controls the mapping from blits to/from the screen.
+	A new function, SDL_SetPalette() has been added to change
+	logical and physical palettes separately. SDL_SetColors() works
+	just as before, and is equivalent to calling SDL_SetPalette() with
+	a flag argument of (SDL_LOGPAL|SDL_PHYSPAL).
+
+	SDL_BlitSurface() no longer modifies the source rectangle, only the
+	destination rectangle. The width/height members of the destination
+	rectangle are ignored, only the position is used.
+
+	The old source clipping function SDL_SetClipping() has been replaced
+	with a more useful function to set the destination clipping rectangle:
+		SDL_bool SDL_SetClipRect(SDL_Surface *surface, SDL_Rect *rect)
+		
+	Added a function to see what subsystems have been initialized:
+		Uint32 SDL_WasInit(Uint32 flags)
+
+	The Big Alpha Flip: SDL now treats alpha as opacity like everybody
+	else, and not as transparency:
+
+	A new cpp symbol: SDL_ALPHA_OPAQUE is defined as 255
+	A new cpp symbol: SDL_ALPHA_TRANSPARENT is defined as 0
+	Values between 0 and 255 vary from fully transparent to fully opaque.
+
+	New functions:
+	SDL_DisplayFormatAlpha()
+	    Returns a surface converted to a format with alpha-channel
+	    that can be blit efficiently to the screen. (In other words,
+	    like SDL_DisplayFormat() but the resulting surface has
+	    an alpha channel.)  This is useful for surfaces with alpha.
+	SDL_MapRGBA()
+	    Works as SDL_MapRGB() but takes an additional alpha parameter.
+	SDL_GetRGBA()
+	    Works as SDL_GetRGB() but also returns the alpha value
+	    (SDL_ALPHA_OPAQUE for formats without an alpha channel)
+
+	Both SDL_GetRGB() and SDL_GetRGBA() now always return values in
+	the [0..255] interval. Previously, SDL_GetRGB() would return
+	(0xf8, 0xfc, 0xf8) for a completely white pixel in RGB565 format.
+	(N.B.: This is broken for bit fields < 3 bits.)
+
+	SDL_MapRGB() returns pixels in which the alpha channel is set opaque.
+
+	SDL_SetAlpha() can now be used for both setting the per-surface
+	alpha, using the new way of thinking of alpha, and also to enable
+	and disable per-pixel alpha blending for surfaces with an alpha
+	channel:
+		To disable alpha blending:
+			SDL_SetAlpha(surface, 0, 0);
+		To re-enable alpha blending:
+			SDL_SetAlpha(surface, SDL_SRCALPHA, 0);
+	Surfaces with an alpha channel have blending enabled by default.
+
+	SDL_SetAlpha() now accepts SDL_RLEACCEL as a flag, which requests
+	RLE acceleration of blits, just as like with SDL_SetColorKey().
+	This flag can be set for both surfaces with an alpha channel
+	and surfaces with an alpha value set by SDL_SetAlpha().
+	As always, RLE surfaces must be locked before pixel access is
+	allowed, and unlocked before any other SDL operations are done
+	on it.
+
+	The blit semantics for surfaces with and without alpha and colorkey
+	have now been defined:
+
+	RGBA->RGB:
+	    SDL_SRCALPHA set:
+		alpha-blend (using alpha-channel).
+		SDL_SRCCOLORKEY ignored.
+	    SDL_SRCALPHA not set:
+		copy RGB.
+		if SDL_SRCCOLORKEY set, only copy the pixels matching the
+		RGB values of the source colour key, ignoring alpha in the
+		comparison.
+
+	RGB->RGBA:
+	    SDL_SRCALPHA set:
+		alpha-blend (using the source per-surface alpha value);
+		set destination alpha to opaque.
+	    SDL_SRCALPHA not set:
+		copy RGB, set destination alpha to opaque.
+	    both:
+		if SDL_SRCCOLORKEY set, only copy the pixels matching the
+		source colour key.
+
+	RGBA->RGBA:
+	    SDL_SRCALPHA set:
+		alpha-blend (using the source alpha channel) the RGB values;
+		leave destination alpha untouched. [Note: is this correct?]
+		SDL_SRCCOLORKEY ignored.
+	    SDL_SRCALPHA not set:
+		copy all of RGBA to the destination.
+		if SDL_SRCCOLORKEY set, only copy the pixels matching the
+		RGB values of the source colour key, ignoring alpha in the
+		comparison.
+
+	RGB->RGB: 
+	    SDL_SRCALPHA set:
+		alpha-blend (using the source per-surface alpha value).
+	    SDL_SRCALPHA not set:
+		copy RGB.
+	    both:
+		if SDL_SRCCOLORKEY set, only copy the pixels matching the
+		source colour key.
+
+	As a special case, blits from surfaces with per-surface alpha
+	value of 128 (50% transparency) are optimised and much faster
+	than other alpha values. This does not apply to surfaces with
+	alpha channels (per-pixel alpha).
+
+	New functions for manipulating the gamma of the display have
+	been added:
+		int SDL_SetGamma(float red, float green, float blue);
+		int SDL_SetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue);
+		int SDL_GetGammaRamp(Uint8 *red, Uint8 *green, Uint8 *blue);
+	Gamma ramps are tables with 256 entries which map the screen color
+	components into actually displayed colors.  For an example of
+	implementing gamma correction and gamma fades, see test/testgamma.c
+	Gamma control is not supported on all hardware.
+
+1.1.4:
+	The size of the SDL_CDtrack structure changed from 8 to 12 bytes
+	as the size of the length member was extended to 32 bits.
+
+        You can now use SDL for 2D blitting with a GL mode by passing the
+	SDL_OPENGLBLIT flag to SDL_SetVideoMode().  You can specify 16 or
+	32 bpp, and the data in the framebuffer is put into the GL scene
+	when you call SDL_UpdateRects(), and the scene will be visible
+	when you call SDL_GL_SwapBuffers().
+
+	Run the "testgl" test program with the -logo command line option
+	to see an example of this blending of 2D and 3D in SDL.
+
+1.1.3:
+	Added SDL_FreeRW() to the API, to complement SDL_AllocRW()
+
+	Added resizable window support - just add SDL_RESIZABLE to the
+	SDL_SetVideoMode() flags, and then wait for SDL_VIDEORESIZE events.
+	See SDL_events.h for details on the new SDL_ResizeEvent structure.
+
+	Added condition variable support, based on mutexes and semaphores.
+		SDL_CreateCond()
+		SDL_DestroyCond()
+		SDL_CondSignal()
+		SDL_CondBroadcast()
+		SDL_CondWait()
+		SDL_CondTimedWait()
+	The new function prototypes are in SDL_mutex.h
+
+	Added counting semaphore support, based on the mutex primitive.
+		SDL_CreateSemaphore()
+		SDL_DestroySemaphore()
+		SDL_SemWait()
+		SDL_SemTryWait()
+		SDL_SemWaitTimeout()
+		SDL_SemPost()
+		SDL_SemValue()
+	The new function prototypes are in SDL_mutex.h
+
+	Added support for asynchronous blitting.  To take advantage of this,
+	you must set the SDL_ASYNCBLIT flag when setting the video mode and
+	creating surfaces that you want accelerated in this way.  You must
+	lock surfaces that have this flag set, and the lock will block until
+	any queued blits have completed.
+
+	Added YUV video overlay support.
+	The supported YUV formats are: YV12, IYUV, YUY2, UYVY, and YVYU.
+	This function creates an overlay surface:
+		SDL_CreateYUVOverlay()
+	You must lock and unlock the overlay to get access to the data:
+		SDL_LockYUVOverlay() SDL_UnlockYUVOverlay()
+	You can then display the overlay:
+		SDL_DisplayYUVOverlay()
+	You must free the overlay when you are done using it:
+		SDL_FreeYUVOverlay()
+	See SDL_video.h for the full function prototypes.
+
+	The joystick hat position constants have been changed:
+	Old constant            New constant
+	------------            ------------
+	     0                  SDL_HAT_CENTERED
+	     1                  SDL_HAT_UP
+	     2                  SDL_HAT_RIGHTUP
+	     3                  SDL_HAT_RIGHT
+	     4                  SDL_HAT_RIGHTDOWN
+	     5                  SDL_HAT_DOWN
+	     6                  SDL_HAT_LEFTDOWN
+	     7                  SDL_HAT_LEFT
+	     8                  SDL_HAT_LEFTUP
+	The new constants are bitmasks, so you can check for the
+	individual axes like this:
+		if ( hat_position & SDL_HAT_UP ) {
+		}
+	and you'll catch left-up, up, and right-up.
+
+1.1.2:
+	Added multiple timer support:
+		SDL_AddTimer() and SDL_RemoveTimer()
+
+	SDL_WM_SetIcon() now respects the icon colorkey if mask is NULL.
+
+1.1.0:
+	Added initial OpenGL support.
+	First set GL attributes (such as RGB depth, alpha depth, etc.)
+		SDL_GL_SetAttribute()
+	Then call SDL_SetVideoMode() with the SDL_OPENGL flag.
+	Perform all of your normal GL drawing.
+	Finally swap the buffers with the new SDL function:
+		SDL_GL_SwapBuffers()
+	See the new 'testgl' test program for an example of using GL with SDL.
+
+	You can load GL extension functions by using the function:
+		SDL_GL_LoadProcAddress()
+
+	Added functions to initialize and cleanup specific SDL subsystems:
+		SDL_InitSubSystem() and SDL_QuitSubSystem()
+
+	Added user-defined event type:
+		typedef struct {
+        		Uint8 type;
+        		int code;
+        		void *data1;
+        		void *data2;
+		} SDL_UserEvent;
+	This structure is in the "user" member of an SDL_Event.
+
+	Added a function to push events into the event queue:
+		SDL_PushEvent()
+
+	Example of using the new SDL user-defined events:
+	{
+		SDL_Event event;
+
+		event.type = SDL_USEREVENT;
+		event.user.code = my_event_code;
+		event.user.data1 = significant_data;
+		event.user.data2 = 0;
+		SDL_PushEvent(&event);
+	}
+
+	Added a function to get mouse deltas since last query:
+		SDL_GetRelativeMouseState()
+
+	Added a boolean datatype to SDL_types.h:
+		SDL_bool = { SDL_TRUE, SDL_FALSE }
+
+	Added a function to get the current audio status:
+		SDL_GetAudioState();
+	It returns one of:
+		SDL_AUDIO_STOPPED,
+		SDL_AUDIO_PLAYING,
+		SDL_AUDIO_PAUSED
+
+	Added an AAlib driver (ASCII Art) - by Stephane Peter.
+
+1.0.6:
+	The input grab state is reset after each call to SDL_SetVideoMode().
+	The input is grabbed by default in fullscreen mode, and ungrabbed in
+	windowed mode.  If you want to set input grab to a particular value,
+	you should set it after each call to SDL_SetVideoMode().
+
+1.0.5:
+	Exposed SDL_AudioInit(), SDL_VideoInit()
+	Added SDL_AudioDriverName() and SDL_VideoDriverName()
+
+	Added new window manager function:
+		SDL_WM_ToggleFullScreen()
+	This is currently implemented only on Linux
+
+	The ALT-ENTER code has been removed - it's not appropriate for a
+	lib to bind keys when they aren't even emergency escape sequences.
+
+	ALT-ENTER functionality can be implemented with the following code:
+
+	int Handle_AltEnter(const SDL_Event *event)
+	{
+	    if ( event->type == SDL_KEYDOWN ) {
+	        if ( (event->key.keysym.sym == SDLK_RETURN) &&
+	             (event->key.keysym.mod & KMOD_ALT) ) {   
+	                SDL_WM_ToggleFullScreen(SDL_GetVideoSurface());
+	                return(0);
+	        }
+	    }
+	    return(1);
+	}
+	SDL_SetEventFilter(Handle_AltEnter);
+
+1.0.3:
+	Under X11, if you grab the input and hide the mouse cursor,
+	the mouse will go into a "relative motion" mode where you
+	will always get relative motion events no matter how far in
+	each direction you move the mouse - relative motion is not
+	bounded by the edges of the window (though the absolute values
+	of the mouse positions are clamped by the size of the window).
+	The SVGAlib, framebuffer console, and DirectInput drivers all
+	have this behavior naturally, and the GDI and BWindow drivers
+	never go into "relative motion" mode.
+
+1.0.2:
+	Added a function to enable keyboard repeat:
+		SDL_EnableKeyRepeat()
+
+	Added a function to grab the mouse and keyboard input
+		SDL_WM_GrabInput()
+
+	Added a function to iconify the window.
+		SDL_WM_IconifyWindow()
+	If this function succeeds, the application will receive an event
+	signaling SDL_APPACTIVE event 
+
+1.0.1:
+	Added constants to SDL_audio.h for 16-bit native byte ordering:
+		AUDIO_U16SYS, AUDIO_S16SYS
+
+1.0.0:
+	New public release
+
+Version 0.11:
+
+0.11.5:
+	A new function SDL_GetVideoSurface() has been added, and returns
+	a pointer to the current display surface.
+
+	SDL_AllocSurface() has been renamed SDL_CreateRGBSurface(), and
+	a new function SDL_CreateRGBSurfaceFrom() has been added to allow
+	creating an SDL surface from an existing pixel data buffer.
+
+	Added SDL_GetRGB() to the headers and documentation.
+
+0.11.4:
+	SDL_SetLibraryPath() is no longer meaningful, and has been removed.
+
+0.11.3:
+	A new flag for SDL_Init(), SDL_INIT_NOPARACHUTE, prevents SDL from
+	installing fatal signal handlers on operating systems that support
+	them.
+
+Version 0.9:
+
+0.9.15:
+	SDL_CreateColorCursor() has been removed.  Color cursors should
+	be implemented as sprites, blitted by the application when the
+	cursor moves.  To get smooth color cursor updates when the app
+	is busy, pass the SDL_INIT_EVENTTHREAD flag to SDL_Init().  This
+	allows you to handle the mouse motion in another thread from an
+	event filter function, but is currently only supported by Linux
+	and BeOS.  Note that you'll have to protect the display surface
+	from multi-threaded access by using mutexes if you do this.
+
+	Thread-safe surface support has been removed from SDL.
+	This makes blitting somewhat faster, by removing SDL_MiddleBlit().
+	Code that used SDL_MiddleBlit() should use SDL_LowerBlit() instead.
+	You can make your surfaces thread-safe by allocating your own
+	mutex and making lock/unlock calls around accesses to your surface.
+
+0.9.14:
+	SDL_GetMouseState() now takes pointers to int rather than Uint16.
+
+	If you set the SDL_WINDOWID environment variable under UNIX X11,
+	SDL will use that as the main window instead of creating it's own.
+	This is an unsupported extension to SDL, and not portable at all.
+
+0.9.13:
+	Added a function SDL_SetLibraryPath() which can be used to specify
+	the directory containing the SDL dynamic libraries.  This is useful
+	for commercial applications which ship with particular versions
+	of the libraries, and for security on multi-user systems.
+	If this function is not used, the default system directories are 
+	searched using the native dynamic object loading mechanism.
+
+	In order to support C linkage under Visual C++, you must declare
+	main() without any return type:
+		main(int argc, char *argv[]) {
+			/* Do the program... */
+			return(0);
+		}
+	C++ programs should also return a value if compiled under VC++.
+
+	The blit_endian member of the SDL_VideoInfo struct has been removed.
+
+	SDL_SymToASCII() has been replaced with SDL_GetKeyName(), so there
+	is now no longer any function to translate a keysym to a character.
+
+	The SDL_keysym structure has been extended with a 'scancode' and
+	'unicode' member.  The 'scancode' is a hardware specific scancode
+	for the key that was pressed, and may be 0.  The 'unicode' member
+	is a 16-bit UNICODE translation of the key that was pressed along
+	with any modifiers or compose keys that have been pressed.
+	If no UNICODE translation exists for the key, 'unicode' will be 0.
+
+	Added a function SDL_EnableUNICODE() to enable/disable UNICODE
+	translation of character keypresses.  Translation defaults off.
+
+	To convert existing code to use the new API, change code which
+	uses SDL_SymToASCII() to get the keyname to use SDL_GetKeyName(),
+	and change code which uses it to get the ASCII value of a sym to
+	use the 'unicode' member of the event keysym.
+
+0.9.12:
+	There is partial support for 64-bit datatypes.  I don't recommend 
+	you use this if you have a choice, because 64-bit datatypes are not
+	supported on many platforms.  On platforms for which it is supported,
+	the SDL_HAS_64BIT_TYPE C preprocessor define will be enabled, and
+	you can use the Uint64 and Sint64 datatypes.
+
+	Added functions to SDL_endian.h to support 64-bit datatypes:
+	    SDL_SwapLE64(), SDL_SwapBE64(),
+	    SDL_ReadLE64(), SDL_ReadBE64(), SDL_WriteLE64(), SDL_WriteBE64()
+
+	A new member "len_ratio" has been added to the SDL_AudioCVT structure,
+	and allows you to determine either the original buffer length or the
+	converted buffer length, given the other.
+
+	A new function SDL_FreeWAV() has been added to the API to free data
+	allocated by SDL_LoadWAV_RW().  This is necessary under Win32 since
+	the gcc compiled DLL uses a different heap than VC++ compiled apps.
+
+	SDL now has initial support for international keyboards using the
+	Latin character set.
+	If a particular mapping is desired, you can set the DEFAULT_KEYBOARD
+	compile-time variable, or you can set the environment variable 
+	"SDL_KEYBOARD" to a string identifying the keyboard mapping you desire.
+	The valid values for these variables can be found in SDL_keyboard.c
+
+	Full support for German and French keyboards under X11 is implemented.
+
+0.9.11:
+	The THREADED_EVENTS compile-time define has been replaced with the
+	SDL_INIT_EVENTTHREAD flag.  If this flag is passed to SDL_Init(),
+	SDL will create a separate thread to perform input event handling.
+	If this flag is passed to SDL_Init(), and the OS doesn't support 
+	event handling in a separate thread, SDL_Init() will fail.
+	Be sure to add calls to SDL_Delay() in your main thread to allow
+	the OS to schedule your event thread, or it may starve, leading
+	to slow event delivery and/or dropped events.
+	Currently MacOS and Win32 do not support this flag, while BeOS 
+	and Linux do support it.  I recommend that your application only
+	use this flag if absolutely necessary.
+
+	The SDL thread function passed to SDL_CreateThread() now returns a
+	status.  This status can be retrieved by passing a non-NULL pointer
+	as the 'status' argument to SDL_WaitThread().
+
+	The volume parameter to SDL_MixAudio() has been increased in range
+	from (0-8) to (0-128)
+
+	SDL now has a data source abstraction which can encompass a file,
+	an area of memory, or any custom object you can envision.  It uses
+	these abstractions, SDL_RWops, in the endian read/write functions,
+	and the built-in WAV and BMP file loaders.  This means you can load
+	WAV chunks from memory mapped files, compressed archives, network
+	pipes, or anything else that has a data read abstraction.
+
+	There are three built-in data source abstractions:
+	    SDL_RWFromFile(), SDL_RWFromFP(), SDL_RWFromMem()
+	along with a generic data source allocation function:
+	    SDL_AllocRW()
+	These data sources can be used like stdio file pointers with the
+	following convenience functions:
+	    SDL_RWseek(), SDL_RWread(), SDL_RWwrite(), SDL_RWclose()
+	These functions are defined in the new header file "SDL_rwops.h"
+
+	The endian swapping functions have been turned into macros for speed
+	and SDL_CalculateEndian() has been removed.  SDL_endian.h now defines
+	SDL_BYTEORDER as either SDL_BIG_ENDIAN or SDL_LIL_ENDIAN depending on
+	the endianness of the host system.
+
+	The endian read/write functions now take an SDL_RWops pointer
+	instead of a stdio FILE pointer, to support the new data source
+	abstraction.
+
+	The SDL_*LoadWAV() functions have been replaced with a single
+	SDL_LoadWAV_RW() function that takes a SDL_RWops pointer as it's
+	first parameter, and a flag whether or not to automatically 
+	free it as the second parameter.  SDL_LoadWAV() is a macro for
+	backward compatibility and convenience:
+	    SDL_LoadWAV_RW(SDL_RWFromFile("sample.wav", "rb"), 1, ...);
+
+	The SDL_*LoadBMP()/SDL_*SaveBMP() functions have each been replaced
+	with a single function that takes a SDL_RWops pointer as it's
+	first parameter, and a flag whether or not to automatically 
+	free it as the second parameter.  SDL_LoadBMP() and SDL_SaveBMP()
+	are macros for backward compatibility and convenience:
+	    SDL_LoadBMP_RW(SDL_RWFromFile("sample.bmp", "rb"), 1, ...);
+	    SDL_SaveBMP_RW(SDL_RWFromFile("sample.bmp", "wb"), 1, ...);
+	Note that these functions use SDL_RWseek() extensively, and should
+	not be used on pipes or other non-seekable data sources.
+
+0.9.10:
+	The Linux SDL_SysWMInfo and SDL_SysWMMsg structures have been 
+	extended to support multiple types of display drivers, as well as
+        safe access to the X11 display when THREADED_EVENTS is enabled.
+        The new structures are documented in the SDL_syswm.h header file.
+
+	Thanks to John Elliott <jce@seasip.demon.co.uk>, the UK keyboard
+	should now work properly, as well as the "Windows" keys on US
+	keyboards.
+
+	The Linux CD-ROM code now reads the CD-ROM devices from /etc/fstab
+	instead of trying to open each block device on the system.
+	The CD must be listed in /etc/fstab as using the iso9660 filesystem.
+
+	On Linux, if you define THREADED_EVENTS at compile time, a separate
+	thread will be spawned to gather X events asynchronously from the
+	graphics updates.  This hasn't been extensively tested, but it does
+	provide a means of handling keyboard and mouse input in a separate
+	thread from the graphics thread.  (This is now enabled by default.)
+
+	A special access function SDL_PeepEvents() allows you to manipulate
+	the event queue in a thread-safe manner, including peeking at events,
+	removing events of a specified type, and adding new events of arbitrary
+	type to the queue (use the new 'user' member of the SDL_Event type).
+
+	If you use SDL_PeepEvents() to gather events, then the main graphics
+	thread needs to call SDL_PumpEvents() periodically to drive the event
+	loop and generate input events.  This is not necessary if SDL has been 
+	compiled with THREADED_EVENTS defined, but doesn't hurt.
+
+	A new function SDL_ThreadID() returns the identifier associated with
+	the current thread.
+
+0.9.9:
+	The AUDIO_STEREO format flag has been replaced with a new 'channels'
+	member of the SDL_AudioSpec structure.  The channels are 1 for mono
+	audio, and 2 for stereo audio.  In the future more channels may be
+	supported for 3D surround sound.
+
+	The SDL_MixAudio() function now takes an additional volume parameter,
+	which should be set to SDL_MIX_MAXVOLUME for compatibility with the
+	original function.
+
+	The CD-ROM functions which take a 'cdrom' parameter can now be
+	passed NULL, and will act on the last successfully opened CD-ROM.
+
+0.9.8:
+	No changes, bugfixes only.
+	
+0.9.7:
+	No changes, bugfixes only.
+	
+0.9.6:
+	Added a fast rectangle fill function: SDL_FillRect()
+
+	Addition of a useful function for getting info on the video hardware:
+	    const SDL_VideoInfo *SDL_GetVideoInfo(void)
+        This function replaces SDL_GetDisplayFormat().
+
+	Initial support for double-buffering:
+	  Use the SDL_DOUBLEBUF flag in SDL_SetVideoMode()
+	  Update the screen with a new function: SDL_Flip()
+
+	SDL_AllocSurface() takes two new flags:
+	SDL_SRCCOLORKEY means that the surface will be used for colorkey blits
+	  and if the hardware supports hardware acceleration of colorkey blits
+	  between two surfaces in video memory, to place the surface in video
+	  memory if possible, otherwise it will be placed in system memory.
+	SDL_SRCALPHA means that the surface will be used for alpha blits and
+	  if the hardware supports hardware acceleration of alpha blits between
+	  two surfaces in video memory, to place the surface in video memory
+	  if possible, otherwise it will be placed in system memory.
+	SDL_HWSURFACE now means that the surface will be created with the 
+	  same format as the display surface, since having surfaces in video
+	  memory is only useful for fast blitting to the screen, and you can't
+	  blit surfaces with different surface formats in video memory.
+
+0.9.5:
+	You can now pass a NULL mask to SDL_WM_SetIcon(), and it will assume
+	that the icon consists of the entire image.
+
+	SDL_LowerBlit() is back -- but don't use it on the display surface.
+	It is exactly the same as SDL_MiddleBlit(), but doesn't check for
+	thread safety.
+
+	Added SDL_FPLoadBMP(), SDL_FPSaveBMP(), SDL_FPLoadWAV(), which take
+	a FILE pointer instead of a file name.
+
+	Added CD-ROM audio control API:
+	    SDL_CDNumDrives()
+	    SDL_CDName()
+	    SDL_CDOpen()
+	    SDL_CDStatus()
+	    SDL_CDPlayTracks()
+	    SDL_CDPlay()
+	    SDL_CDPause()
+	    SDL_CDResume()
+	    SDL_CDStop()
+	    SDL_CDEject()
+	    SDL_CDClose()
+
+0.9.4:
+	No changes, bugfixes only.
+
+0.9.3:
+	Mouse motion event now includes relative motion information:
+	    Sint16 event->motion.xrel, Sint16 event->motion.yrel
+
+	X11 keyrepeat handling can be disabled by defining IGNORE_X_KEYREPEAT
+	    (Add -DIGNORE_X_KEYREPEAT to CFLAGS line in obj/x11Makefile)
+
+0.9.2:
+	No changes, bugfixes only.
+
+0.9.1:
+	Removed SDL_MapSurface() and SDL_UnmapSurface() -- surfaces are now
+	automatically mapped on blit.
+
+0.8.0:
+	SDL stable release
