#
# Usage cops [-a architecture] [-b bit_bucket] [-s secure_dir] \
# [-m user] [-f filter_file] [-dxvV]
#
# -a specifies the architecure subdirectory you want to run in; you
# must run "make install" to install the appropriate binaries there
#
# -b specifies the "bit bucket", where all the error messages go to.
#
# -d will mail a report only if there have been changes since the
# last one. Only makes sense with the -m flag or by setting the
# MMAIL var below.
#
# -f specifies the cops filter file, which is used for filtering out
# extraneous warning message.
#
# -m tells cops to mail the output to the user specified
#
# -s tells cops where the secure directory is; mostly this is used by
# cops itself, when it is run with the -a flag; it will rerun itself
# with the -a flag's argument as an argument to this.
#
# -x prints out the version number (running out of letters! :-))
#
# -[vV] are the verbose flags. Small "v" says print whatever program
# is running, when it is executed, in the output file; capital
# "V" says print everything to the screen.
#
# Warning! COPS will get confused if you use a command line arg that
# expects an argument and you don't give it one. Don't say I didn't
# warn you :-)
#
# Overall --
#
# Cops will change into the $SECURE/architecture directory, ensure all
# the security programs (listed below) indeed do exist, and run all of the
# security programs. If any of the programs find any security problems, it
# either sends mail to everyone in the $SECURE_USERS list, or saves the results
# in a file $SECURE/architecture/hostname. It then destroys all temporary
# files, and exits the program. Programs that are run (besides this one):
#
# root.chk dev.chk group.chk
# home.chk rc.chk passwd.chk
# is_able.chk pass.chk user.chk
# cron.chk misc.chk ftp.chk
#
# The U-kuang system runs these additional programs:
# init_kuang kuang addto
# clearfiles filewriters members
#
# If this is changed to "NO", the report that cops creates
# will not be deleted and the results will not be mailed to anyone.

#
# Foreign language users can change this (thanks to Wolfgang Denk!):

#
# If this is changed to "YES", then the report will only be mailed
# if it detects a difference between the last report and this one.
# Note that this makes no sense unless the mail is set to "YES" as well.
