This program combines X font alias information from several packages into a
single file that is placed in each specified X font directory DIRECTORY. This
utility is primarily useful to Debian package maintainer scripts. See
update-fonts-dir(8) for more information.
Options:
-h, --help display this usage message and exit
-7, --x11r7-layout use new font layout introduced with X11R7
