    gs2build.patch
        Contains patches for the gs2build build process
        Disables building externals
    perl-util.patch
        Contains a patch to change the tmp folder for gs2build
        This is necessary because the original location of the tmp folder was in the gs2build folder, which contains executables, and as such should be read-only.
        Thus the tmp folder has been changed to /tmp/greenstone-build

Scripts:
    greenstone
        Sets up the environment for running greenstone-tools
    gli
        Runs greenstone to set up the environment, then runs GLI
    wvWare
        Removes itself from $PATH, then runs wvWare (which will be the system wvWare)

Gotchas:
    derby.jar location
        Must be in the tomcat lib folder instead of the greenstone lib folder
