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

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

DESCRIPTION
       addftinfo  reads  a  troff font file and adds some addi-
       tional 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 param-
       eters 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
       -v prints the version number.

       All other options changes one of the parameters that  is
       used  to derive the heights and depths.  Like the exist-
       ing 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 parame-
       ters to guess the unspecified parameters.  If a  parame-
       ter  is  not  specified  the  default will be used.  The
       defaults are chosen to have the reasonable values for  a
       Times font.
