I re-wrote the wrapper script (wolf3d) to install (symlink) the data to the user's home directory (~/.wolf3d) the first time the script is executed.
It will then check to see if the data is installed (if ~/.wolf3d exists) the next time the script is executed. If it does indeed exist, the installation does not happen again, and it runs the program.
I also modified the COMMENT to be a bit more appropriate, and added a pkg-message alerting the user of possible home directory conflicts.
If anybody feels like my script could be written in a better manner, feel free to write one and submit it.
