pvo@talon.UCS.ORST.EDU (Paul O'Neill) (03/12/91)
I was going to clean this up and post it. It would never have made it to you.
Here it is "dirty."
1st the pet peeve:
Why are so many people throwing out code here w/o their name and date
on it? Just because perl "makes programing fun again" (tm), is no
reason to get sloppy.
2nd the mail summarizer:
I don't know who to attribute this to. It could still use some work.
Output of "ssl.pl -m /var/log/syslog" (can you tell I'm on a Sun?)
looks something like:

I did it a "long" time ago, and it's probably not the pinnacle a perl programming I'd right today. Maybe I just didn't want anyone to know. :-) --tom
