I recently tried the  "messages"  shell  script  (never  used  it
before), and got the error message:

	z[13]: test: argument expected

Turns out that on our machine (Pyramid  98x  OS  4.0),  the  MAIL
variable (at least in the ucb universe) isn't set to anything, so
that messages balks at "if [ -f <nothing> ]; then".

It would be nice to try and anticipate some of the possible error
conditions.  Locally, something like this works:

	#! /bin/sh
	if [ "$MAIL" = "" ]; then
	   if [ "$LOGNAME" = "" ]; then
  	      echo "$0: need MAIL or LOGNAME variables set"
              exit 1
           else
	      if [ -d /usr/mail ]; then
  	         MAIL=/usr/mail/$LOGNAME
              else
  	         MAIL=/usr/spool/mail/$LOGNAME
              fi
           fi
	fi
	...
 
 ALSO, does "trim-headers" work  for  anybody  else?  If  I  pass
 something like:

	<text of article or letter>

 That's exactly what I get back (ie, no "trimming"  of  the  mail
 headers).
