* 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.
