Name
       addftinfo - add font metrics to troff fonts for use with groff

Synopsis
       addftinfo [-asc-height n] [-body-depth n] [-body-height n]
		 [-cap-height n] [-comma-depth n] [-desc-depth n]
		 [-fig-height n] [-x-height n] resolution unit-width font

       addftinfo -v
       addftinfo --version

Description
       addftinfo reads an AT&T troff font description file font, adds
       additional font metric information required by GNU troff(1), and writes
       the combined result to the standard output.  The information added is
       derived from the font's existing parameters and assumptions about
       traditional troff names for characters.	Among the font metrics added
       are the heights and depths of characters (how far each extends
       vertically above and below the baseline).  The resolution and
       unit-width arguments should be the same as the corresponding parameters
       in the DESC file.  font is the name of the file describing the font; if
       font ends with “I”, the font is assumed to be oblique (or italic).

Options
       --help displays a usage message, while -v and --version show version
       information; all exit afterward.

       All other options change parameters that are used to derive the heights
       and depths.  Like the existing quantities in the font description file,
       each value n is in scaled points, inches/resolution for a font whose
       type size is unit-width; see groff_font(5).

       -asc-height n
	      height of characters with ascenders, such as “b”, “d”, or “l”

       -body-depth n
	      depth of characters such as parentheses

       -body-height n
	      height of characters such as parentheses

       -cap-height n
	      height of uppercase letters such as “A”

       -comma-depth n
	      depth of a comma

       -desc-depth n
	      depth of characters with descenders, such as “p”, “q”, or “y”

       -fig-height
	      height of figures (numerals)

       -x-height n
	      height of lowercase letters without ascenders such as “x”

       addftinfo makes no attempt to use the specified parameters to infer
       unspecified parameters.	If a parameter is not specified, the default
       will be used.  The defaults are chosen to produce reasonable values for
       a Times font.
