trig_protect_paranoid.py #1

# Task: form trigger that refuses "p4 protect" entries that
#	give permissions to "user *"
#
# will work on 2004.2 (and later) Perforce servers, but you
# need to remember to install the trigger thusly:
# (p4 triggers line follows - the '#' is a comment char for Python.)
#        example  in  protect "python  /path/to/scripts/on/server/machine/trig_protect_paranoid.py  --formfile %formfile%"

# vi: set ts=4:
# vim: set ts=4:
#
# num of calls to 'p4': 0
# status: tested on Darwin Mac OS X using python 2.3
