Updated some documentation, added a FIXME.

 * This code shows how to read a zipfile included in an app's binary.

 * Unless otherwise stated, the rest of PhysicsFS falls under the zlib license.

 *  This file was written by Ryan C. Gordon. (icculus@icculus.org).

 * Compile this program and then attach a .zip file to the end of the
 *  compiled binary.
 * On Linux, something like this will build the final binary:
 *   gcc -o selfextract.tmp selfextract.c -lphysfs && \
 *   cat selfextract.tmp myzipfile.zip >> selfextract && \
 *   chmod a+x selfextract && \
 *   rm -f selfextract.tmp
 * This may not work on all platforms, and it probably only works with
 *  .zip files, since they are designed to be appended to another file.
