        !            11: .I loadfont
        !            12: program lets the user load and remove fonts from the terminal's cache.

        !            14: the user. The command line arguments have the following meanings:
        !            15: .PP
        !            16: .TP 12
        !            17: \fB\-r\fR
        !            18: Removes the given font from the terminal's cache.
        !            19: .PP
        !            20: .TP 12
        !            21: \fB\-p\fR
        !            22: Sets default search path for font files. If this isn't set,
        !            23: it defaults to $DMD/termfonts. All the file names in this directory
        !            24: are put in the load submenu.
        !            25: .TP 12
        !            26: \fB\-s\fR
        !            27: Makes loadfont stay running after executing the earlier command line options.

        !            31: Causes loadfont to be cached in the 630 MTG cache system. When
        !            32: this option is used, the loadfont program will remain in the
        !            33: terminal after the program exits. Then, the next time loadfont
        !            34: is executed, it will not have to be downloaded again.
        !            35: .sp
        !            36: Another effect of downloading loadfont with the \-c option is
        !            37: that it can be executed in more than one window without
        !            38: additional downloading.

        !            43: .PP
        !            44: If a \f3file\f1 argument and/or the
        !            45: \f3\-r\f1 option are given, loadfont will exit after
        !            46: loading/removing the specified fonts, unless the \f3\-s\f1 is
        !            47: also given to make it stay running.
        !            48: .PP
        !            49: The user interacts with
        !            50: .I loadfont
        !            51: by using a button 2 menu and, when prompted, the keyboard.

        !            57: The fonts listed are all the files in the default search directory.
        !            58: If the first item, Keyboard, is selected, the user is prompted
        !            59: for the name of a font file to download.

        !            72: While a font is downloading, the button 2 menu will have only
        !            73: one item, Terminate Download. Selecting it will stop the download
        !            74: and switch the user back to the original menu.
