# original MakeTeXPK -- make a new PK font, because one wasn't found.
# Version of 12dec94.
# (If you change or delete the word `original' on the previous line,
# installation won't write this MakeTeXPK over yours.)
# This script must echo the name of the generated PK file (and nothing
# else) to standard output. Yes, this is different from the original dvips.
# Parameters:
#   name dpi bdpi magnification [mode [destdir]]
#   `name' is the base name of the font, such as `cmr10'.
#   `dpi' is the resolution the font is needed at.
#   `bdpi' is the base resolution, used to intuit the mode to use.
#   `magnification' is a string to pass to MF as the value of `mag'.
#   `mode', if supplied, is the mode to use. Unless it's `default', in
#     which case we guess. (This is so people can specify a destdir
#     without a mode.)
#   `destdir', if supplied, is either the absolute directory name to use
#     (if it starts with a /) or relative to the default DESTDIR (if not).

# The root of where to put the new file. (Using the sh construct
# ${var=value} is the tersest construct that lets an environment
# variable `var' override the value given here.)
