#   This script file makes a new TeX TFM font, because one wasn't
#   found.  Usage:
#
#   MakeTFM name [mode]
#
#   `name' is the name of the font, such as `cmr10'.
#   `mode', if supplied, is the mode to use.
#
#   Note that this file must execute Metafont, and place the result 
#   in the correct location.
#
#   Of course, it needs to be set up for your site.
#
# TEMPDIR needs to be unique for each process because of the possibility
# of simultaneous processes running this script.
