.SH DESCRIPTION
.\" ====================================================================
.
.B 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
.I res
and
.I unitwidth
arguments should be the same as the corresponding parameters in the
DESC file;
.I font
is the name of the file describing the font;
if
.I font
ends with
.B I
the font will be assumed to be italic.
.
.
.\" ====================================================================
.SH OPTIONS
.\" ====================================================================
.
.B \-v
prints the version number.
.
.
.LP
All other options change one of the parameters that are used to derive
the heights and depths.
.
Like the existing quantities in the font file, each
.I value
is in
.RI inches/ res
for a font whose point size is
.IR unitwidth .
.
.I param-option
must be one of:
.
.TP
.B \-x\-height
The height of lowercase letters without ascenders such as x.
.
.TP
.B \-fig\-height
The height of figures (digits).
.
.TP
.B \-asc\-height
The height of characters with ascenders, such as b, d or l.
.
.TP
.B \-body\-height
The height of characters such as parentheses.
.
.TP
.B \-cap\-height
The height of uppercase letters such as A.
.
.TP
.B \-comma\-depth
The depth of a comma.
.
.TP
.B \-desc\-depth
The depth of characters with descenders, such as p, q, or y.
.
.TP
.B \-body\-depth
The depth of characters such as parentheses.
.
.
.LP
.B 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.
