# Revised: November 23, 2004
# Version 2.0
# Purpose: Used to find executable files in students
#          home directories. Even if they are renamed.
# Limitations: Currently the script does not have the
# ability to look inside compressed files.  I was thinking
# that some day I would add this to the script but you
# could just grep for compressed.
# Special thanks to Paul Massey and Joe Cicero. 
# Without them I would just be another linux noobie.
