mktextfm is used to generate a tfm file from the M ETAFONT source files for font, if possible. If destdir is given, the generated file will be installed there, otherwise a (rather complicated) heuristic is used.
The name of the generated file is printed on standard output.
mktextfm accepts the following options:
A directory name. If the directory is absolute, it is used as-is. Otherwise, it is appended to the root destination directory set in the script.
Print help message and exit.
