 Its really great to have an 'mkdep' with Umax 4.3

 To test it, I 'cd'ed to a source directory and entered 'make depend'

 Sure enough, it compiled all of my source code, and removed all of the
dependencies from Makefile.

  We really shouldn't need to do it this way, but here's a 'mkdep'
that seems to work:
  (I used to use this with Umax 4.2).

#! /bin/sh
# This is a shell archive.  Remove anything before this line, then unpack
# it by saving it into a file and typing "sh file".  To overwrite existing
# files, type "sh file -c".  You can also feed this as standard input via
# unshar, or by typing "sh <file", e.g..  If this archive is complete, you
# will see the following message at the end:
#		"End of shell archive."
# Contents:  mkdep

if test -f 'mkdep' -a "${1}" != "-c" ; then 
  echo shar: Will not clobber existing file \"'mkdep'\"
else
echo shar: Extracting \"'mkdep'\" \(2902 characters\)
