# check_perms - 06/14/93
#
# 05/07/2009 jfs Fixed use of quotes in check_perms (Savannah bug #26479)
# 08/14/2003 jfs Added OUTPUTMETHOD to dependancies
# 05/01/2003 jfs Fixed dependancies
# 11/05/2002 jfs Small fix to prevent shell expansion to ocur while testing
# filenames (discovered due a broken self-made package that
# created a /usr/bin/*config directory, ouch.)
# ??/??/1999 ARC Changed echo to message and limited giving warnings if owner
# of files is 'bin'
# 04/28/1993 dls Added '-L' option to 'ls' so we get permissions from
# file instead of symbolic link.
