# newrm--A replacement for the existing rm command.
#   This script provides a 
#   rudimentary unremove capability by creating and utilizing a new 
#   directory within the user's home directory. It can handle directories
#   of content as well as individual files. If the user specifies
#   the -f flag, files are removed and NOT archived.

# Big Important Warning: You'll want a cron job or something similar to keep 
#   the trash directories tamed. Otherwise, nothing will ever actually
#   be deleted from the system, and you'll run out of disk space!
