I'll just pick one of Scott's questions:

You might look into scan format strings and form files.  They're a nice
way to pull out exactly the header information your shell script needs.
(I used to use "sed" and "awk" to parse "scan" output--what a pain!)
With this, your shell/awk/whatever auto-filer can probably get to the real
job more efficiently.

Here's a quick example of a format string that prints the message number
in a field of width 4, then a space.  After that, it prints the "Sender:"
field, if the message has one--otherwise, it prints the "From:" field.

	$ scan -format "%4(msg) %<{sender}%{sender}%|%{from}%>" last:5
	1146 "Jerry Peek" <jdpeek>
	1147 Rick Amory <RAMORY@MVUS.BITNET>
	1148 "Wilbur, Orville" <orwilbur@monk.ncs.syr.edu>
	1151 EAMYLON@SUNSET.CAS.SYR.EDU (Edwin A. Mylon)
	1152 mh-users-request@ICS.UCI.EDU

There's a lot more to this.  For instance, the %(friendly) escape gives
just addresses without the users' "real" names.  The mh-format(5) manual
page will get you going on this (if you aren't, already).
