RE: Three-Line service comments

If I'm using 30-year old tools like sed and awk then I will make such
allowances for their limitations, but as Adrian indicated, perl has no
problem with this.  I was just hoping cfengine's own facilities would be
sufficient for the task.

This seems to do the trick, removing the comments and most common
variants:

   !GnatsServers::
   { /etc/inet/inetd.conf
      SetScript "perl -00 -pi -e 'BEGIN{pop};s/((\n#)*\n#
GNATS(\n#)*)*\n.*gnatsd//'"
      RunScriptIfLineMatching "support.*gnatsd$"
   }

Thanks,
  Tim

practical.
