#
#   This script file makes a new TeX PK font, because one wasn't found.
#
#   It must echo the name of the generated PK file (and nothing else) to
#   standard output or to the designated file descriptor.
#   Yes, this is different from the original dvips.
#
#   Parameters are:
#
#   name dpi bdpi magnification [mode [destdir [redirect]]]
#
#   `name'          is the name of the font, such as `cmr10'.
#   `dpi'           is the resolution the font is needed at.
#   `bdpi'          is the base resolution, useful for figuring out the mode to
#                   make the font in.
#   `magnification' is a string to pass to MF as the magnification.
#   `mode'          (if supplied) is the mode to use.  If it's `default,'
#                   then we guess.
#   `destdir'       (if supplied) is the absolute directory name to use.
#   `redirect'      (if supplied) is a string of the form '>&n', where n is the
#                   number of the file descriptor which is to receive,
#                   instead of stdout, the name of the newly created pk file.
#
#   Note that this file must execute Metafont, and then gftopk,
#   and place the result in the correct location for the PostScript
#   driver to find it subsequently.  If this doesn't work, it will
#   be evident because this file will be invoked over and over again.
#
#   Of course, it needs to be set up for your site.
