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 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
    -v prints the version number.

    All other 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.
