+.TH LOADFONT 1 "630 MTG"
+.XE "loadfont"
+.SH NAME
+loadfont \- font managing program
+.SH SYNOPSIS
+.B 
+loadfont [\-r name,name...] [\-p directory] [\-s] [\-c] [file...]
+.SH DESCRIPTION
+The
+.I loadfont
+program lets the user load and remove fonts from the terminal's cache.
+It will download its terminal side which interacts with
+the user. The command line arguments have the following meanings:
+.PP
+.TP 12
+\fB\-r\fR
+Removes the given font from the terminal's cache.
+.PP
+.TP 12
+\fB\-p\fR
+Sets default search path for font files. If this isn't set,
+it defaults to $DMD/termfonts. All the file names in this directory
+are put in the load submenu.
+.TP 12
+\fB\-s\fR
+Makes loadfont stay running after executing the earlier command line options.
+.PP
+.TP 12
+\fB\-c\fR
+Causes loadfont to be cached in the 630 MTG cache system. When
+this option is used, the loadfont program will remain in the
+terminal after the program exits. Then, the next time loadfont
+is executed, it will not have to be downloaded again.
+.sp
+Another effect of downloading loadfont with the \-c option is
+that it can be executed in more than one window without
+additional downloading.
+.PP
+.TP 12
+\fBfile\fR
+Loads the given font file into the terminal's cache.
+.PP
+If a \f3file\f1 argument and/or the
+\f3\-r\f1 option are given, loadfont will exit after
+loading/removing the specified fonts, unless the \f3\-s\f1 is
+also given to make it stay running.
+.PP
+The user interacts with
+.I loadfont
+by using a button 2 menu and, when prompted, the keyboard.
+When button 2 is depressed, a menu with the following items appears.
+.PP
+.TP 8
+\fBLoad\fR
+Load has a submenu of fonts that can be downloaded.
+The fonts listed are all the files in the default search directory.
+If the first item, Keyboard, is selected, the user is prompted
+for the name of a font file to download.
+.PP
+.TP 8
+\fBRemove\fR
+Remove has a submenu of all the fonts in the terminal's cache.
+Selecting one will remove it from the cache and free the memory
+it was using. Fonts in ROM or being used by another process
+will be greyed in the menu and cannot be removed.
+.PP
+.TP 8
+\fBQuit\fR
+Will make the program exit.
+.PP
+While a font is downloading, the button 2 menu will have only
+one item, Terminate Download. Selecting it will stop the download
+and switch the user back to the original menu.
+.PP
+The three fonts in ROM, resident to the 630 MTG, are called "small
+font," "medium font," and "large font."  Brief descriptions of these
+fonts follow.
+.PP
+In the tables, 
+.I  cell size
+indicates the dimensions of the rectangle containing the character
+image.  All the characters in a particular font have the same cell size.
+.I Character size
+is the dimension of the largest character in the font.  
+.I Max chars 
+indicates how many characters in that font size will fit 
+horizontally and vertically in a full screen
+window.  See the section on fonts in the 
+\f2630 MTG Software Development Guide\f1
+for more information on font data structures.

+.SH WARNING
+.P
+Fonts that do not have 128 characters require the proper
+parity setting when used in the default window process in the
+non-layers environment. This is needed because a mod is done
+on characters received from the host with the number of
+characters in the font being used.
+.P
+This implies that parity bits are ignored for fonts with
+exactly 128 characters, since c&0x7F == c%128. Fonts with less
+than 128 characters need identical parity settings on the host
+and in the terminal so that parity bits get stripped properly.
+Characters with more than 128 characters require 8 bits with
+no parity on both the host and in the terminal, because the
+eighth bit is used to access characters greater than
+128.
