  Create a PK font.

--dpi DPI           use resolution DPI.
--bdpi BDPI         use base resolution BDPI.
--mag MAG           use magnificiation MAG.
--mfmode MODE       use MODE as the METAFONT mode.
--destdir DESTDIR   write fonts in DESTDIR.

Try to create a PK file for NAME at resolution DPI, with an assumed
device base resolution of BDPI, and a Metafont \`mag' of MAG. Use MODE
for the METAFONT mode.  Use DESTDIR for the root of where to install
into, either the absolute directory name to use (if it starts with a
/) or relative to the default DESTDIR (if not). 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."
