trig_protect_paranoid.p4ruby #2

# 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 Ruby.)
#	 example  in  protect "ruby  /Users/jeffbowles/work/ruby-work/contracts/tmp-trigger-scripts/trig_protect_paranoid.p4ruby  --formfile %formfile% --formname %formname%"

#
# num of calls to 'p4': 0
# status: tested on Darwin Mac OS X using ruby (no P4API needed!)
