-<h2> SDL rwops </h2> Example to make an SDL_rwops interface.

-<h3> Source </h3>
-
-<P>
- The example sources of the <a href="zziplib.html">zziplib library</a>
- are usually put under the <a href="COPYING.ZLIB">ZLIB license</a> so
- that you can reuse the code freely in your own projects. Here we talk
- about the example that might be most useful for
- <a href="http://libsdl.org">SDL</a> based programs.
- Just copy the two files
- <a href="SDL_rwops_zzip.h">SDL_rwops_zzip.h</a>
- and
- <a href="SDL_rwops_zzip.c">SDL_rwops_zzip.c</a>
- to the directory with your other project sources, and make sure
- to link it somehow to your programs. I did not make the effort to
- create a separate library out of it - it would just export one
- single function <tt>SDL_RWFromZZIP</tt> that has the same call-synopsis
- like <tt>SDL_RWFromFile</tt> (but it can not (yet) write a zip-file).
-</P>
-
-<P>
- The source file <a href="SDL_rwops_zzip.c">SDL_rwops_zzip.c</a> is
- quite short - it just stores a ZZIP_FILE handle in the userdata
- field of the <tt>SDL_rwops</tt> structure. The SDL'rwop calls will then
- fetch that pointer and call the corresponding functions from the
- <a href="zziplib.html">zziplib library</a>. Most of the glue code
- is in the <tt>SDL_RWFromZZIP</tt> function that allocates an
- <tt>SDL_rwops</tt> structure and fills the handler-functions
- into the callback fields.
-</P>

-<h3> Usage </h3>
-
-<P>
- If you link this file to your project, remember that your executables
- do now have additional dependencies - not only -lzzip to link with
- the <a href="zziplib.html">zziplib library</a> - do not forget to
- link with zlib library via -lz. Of course, there is a lib-config
- script that you can use: `zzip-config --libs` will return these
- linker-infos (unless you have a native-windows system - it is
- shell-script).
-</P>
-
-<P>
- As an example, replace that <tt>SDL_RWFromFile</tt> that accesses your
- game-graphic files - these files are stored in shared/myapp
- of course where they belong. When you've done that
- then go to X/share/myapp and
-<br><code>&nbsp;&nbsp;&nbsp;
- `(cd graphics/ && zip -9r ../graphics.zip .)` </code><br>
- and rename the graphics/ subfolder - and still all your files
- are found: a filepath like X/shared/graphics/game/greetings.bmp
- will open X/shared/graphics.zip and return the zipped file
- game/greetings.bmp in the zip-archive (for reading that is).
-</P>

-<h3> Test </h3>
-
-<P>
- The <a href="zziplib.html">zziplib</a> configure script does not
- look for <a href="http://libsdl.org">SDL</a>. If you know that
- you have <a href="http://libsdl.org">SDL</a> installed
- then you can check this <tt>SDL_rwops</tt> example by using
- <code><nobr>`make testsdl`</nobr></code>. This will compile the
- two source files <a href="SDL_rwops_zzip.c">SDL_rwops_zzip.c</a>
- and <a href="SDL_rwops_zzcat.c">SDL_rwops_zzcat.c</a> to be linked
- together into an executable called <code>zzcatsdl</code>. The test
- will continue with a <code><nobr>`zzcatsdl test/README`</nobr></code>
- - just like it is done for <code><nobr>`make test3`</nobr></code>.
-</P>
-<P>
- The corresponding section in the <a href="Makefile.am">Makefile.am</a>
- is also an example how to use lib-config scripts to build files. Here
- there is no build-processing that had been tweaked much by automake/autoconf.
- Just use sdl-config and zzip-config to add the needed flags.
-</P>
