#  is_able.chk
#
#   This shell script checks the permissions of all files and directories
# listed in the configuration file "is_able.lst", and prints warning messages
# according to the status of files.  You can specify world or group readability
# or writeability.  See the config file for the format of the configuration
# file.
#
#   Mechanism:  This shell script parses each line from the configure file
# and uses the "is_able.pl" program to check if any of
# the directories in question are writable by world/group.
