NAME
     font - typesetter description tables

SYNOPSIS
     troff -Tname ...

DESCRIPTION
     Typesetter tables for device name are located in directory
     /usr/lib/font/devname. The tables are used by troff and most postpro-
     cessors.

     The tables are ASCII and are read one line at a time. The first word
     on each line is a keyword. The remainder of the line is the value
     associated with that keyword. Lines that begin with unrecognized key-
     words are ignored. Programs that read typesetter tables are free to
     recognize their own collection of keywords provided they parse the
     standard set (below) properly.

     A general description of the typesetter can be found in a file named
     DESC. The standard set of DESC file keywords includes:

     res       Device resolution in dots per inch.

     hor       Smallest unit of horizontal motion.

     vert      Smallest unit of vertical motion.

     sizes     Available point sizes. List must be given in increasing
               numerical order, be terminated with a 0, and can span more
               than one line.

     unitwidth Widths in font tables are given at this point size.

     fonts     Number of font positions followed by the list of default
               fonts. The list can span more than one line.

     charset   List of special characters available in the typesetter.
               Starts on the next line and continues to the end of the DESC
               file.

     The remaining files describe the fonts available on device name. The
     standard set of font table keywords is:

     name        Font name as known to troff.

     special     Indicates the font is special.

     ligatures   Which ligatures (if any) exist of this font. List is ter-
                 minated by 0.

     spacewidth  Width of a space on this font.
