Here's a patch from Chris Pepper for the check_log plugin that may be of 
interest.  He asked that I forward the patch, as he isn't a subscriber.

Best regards,

Ethan,

	I couldn't find a documentation web page for check_log, but the script 
contains this comment:

> # Usage: ./check_log <log_file> <old_log_file> <pattern>

	Unfortunately, that syntax doesn't actually work -- it requires -F -O & 
-q. The usage message needs an update, or (better) the program needs to 
understand the simpler syntax shown on the Usage line.

Regards,

Chris
