# tigercron - 06/13/93
#
# 04/12/2008 jfs Include patch from Chris Lamb that fixes bashism in the script
# (Debian bug #468700)
# 08/15/2003 jfs Now uses run_script instead of SCRIPTDIR/LSCRIPTDIR which
# permits tigercron to execute the most relevant script given
# the $OS/$REL/$ARCH
# Safer creation of the temporary file which includes the
# scripts' results.
# 04/23/2003 jfs Sanity check for the existance of ctrfile, use TigerConfigDir
# instead of CONFIGDIR
# 10/28/2002 jfs Added check of non-comments in output (only available if
# egrep is installed)
# 07/25/2002 jfs Changed TigerInstallDir to .
# 12/26/2001 jfs Modified to provide new ways to compare against previous
# runs: per policy (template) or per run.
# 12/02/2001 jfs Fixed script to properly send out mails with valid
# headers and content
#

# TODO:
# - Study wether or not GPG can be used to automatically sign messages
# sent (using a passwordless key)
# - Make it work with syslog to send the reports (in much the same way
# that sendtologger is used by Tiger when a '-l @syslogserver' is used)
# (Note: This would also help since having it log locally instead of
# could help users running logcheck, at least in Debian)
# - Consider if running checks by absolute filename reference is permitted
# or not
