NAME
          addftinfo - add information to troff font files for use with
          groff

     SYNOPSIS
          addftinfo [ -param value...  ] res unitwidth font

     DESCRIPTION
          addftinfo reads a troff font file and adds some additional
          font-metric information that is used by the groff system.
          The font file with the information added is written on the
          standard output.  The information added is guessed using
          some parametric information about the font and assumptions
          about the traditional troff names for characters.  The main
          information added is the heights and depths of characters.
          The res and unitwidth 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 will be assumed to be italic.

     OPTIONS
          Each of the options changes one of the parameters that is
          used to derive the heights and depths.  Like the existing
          quantities in the font file, each value is in inches/res for
          a font whose point size is unitwidth.  param must be one of:

          x-height
               The height of lowercase letters without ascenders such
               as x.

          fig-height
               The height of figures (digits).

          asc-height
               The height of characters with ascenders, such as b, d
               or l.

          body-height
               The height of characters such as parentheses.

          cap-height
               The height of uppercase letters such as A.

          comma-depth
               The depth of a comma.

          desc-depth
               The depth of characters with descenders, such as p,q,
               or y.

          body-depth
               The depth of characters such as parentheses.

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