DESCRIPTION
       afmtodit creates a font file for use with groff, grops, and gropdf.
       afmtodit is written in Perl; you must have Perl version 5.004 or newer
       installed in order to run afmtodit.

       afm-file is the AFM (Adobe Font Metric) file for the font.

       map-file is a file that says which groff character names map onto each
       PostScript character name; this file should contain a sequence of lines
       of the form
              ps-char groff-char
       where ps-char is the PostScript name of the character and groff-char is
       the groff name of the character (as used in the groff font file).  The
       same ps-char can occur multiple times in the file; each groff-char must
       occur at most once.  Lines starting with `#' and blank lines are
       ignored.  If the file isn't found in the current directory, it is
       searched for in the devps/generate subdirectory of the default font
       directory.

       If a PostScript character is not mentioned in map-file, and a generic
       groff glyph name can't be deduced using the Adobe Glyph List (AGL,
       built into afmtodit), then afmtodit puts the PostScript character into
       the groff font file as an unnamed character which can only be accessed
       by the `\N' escape sequence in a roff document.  In particular, this is
       true for glyph variants named in the form "foo.bar"; all glyph names
       containing one or more periods are mapped to unnamed entities.  If
       option -e is not specified, the encoding defined in the AFM file (i.e.,
       entries with non-negative character codes) is used.  Refer to section
       "Using Symbols" in Groff: The GNU Implementation of troff, the groff
       Texinfo manual, which describes how groff glyph names are constructed.

       Characters not encoded in the AFM file (i.e., entries which have `-1'
       as the character code) are still available in groff; they get glyph
       index values greater than 255 (or greater than the biggest character
       code used in the AFM file in the unlikely case that it is greater than
       255) in the groff font file.  Glyph indices of unencoded characters
       don't have a specific order; it is best to access them with glyph names
       only.

       The groff font file will be output to a file called font, unless the -o
       option is used.

       If there is a downloadable font file for the font, it may be listed in
       the file /usr/local/share/groff/1.22.4/font/devps/download; see
       grops(1).

       If the -i option is used, afmtodit will automatically generate an
       italic correction, a left italic correction and a subscript correction
       for each character (the significance of these parameters is explained
       in _font&section=5">groff_font(5)); these parameters may be specified for individual
       characters by adding to the afm-file lines of the form:
              italicCorrection ps-char n
              leftItalicCorrection ps-char n
              subscriptCorrection ps-char n
       where ps-char is the PostScript name of the character, and n is the
       desired value of the corresponding parameter in thousandths of an em.
       These parameters are normally needed only for italic (or oblique)
       fonts.

OPTIONS
       Whitespace is permitted between a command-line option and its argument.

       -an    Use n as the slant parameter in the font file; this is used by
              groff in the positioning of accents.  By default afmtodit uses
              the negative of the ItalicAngle specified in the AFM file; with
              true italic fonts it is sometimes desirable to use a slant that
              is less than this.  If you find that characters from an italic
              font have accents placed too far to the right over them, then
              use the -a option to give the font a smaller slant.

       -c     Include comments in the font file in order to identify the
              PostScript font.

       -ddesc-file
              The device description file is desc-file rather than the default
              DESC.  If not found in the current directory, the devps
              subdirectory of the default font directory is searched (this is
              true for both the default device description file and a file
              given with option -d).

       -eenc-file
              The PostScript font should be reencoded to use the encoding
              described in enc-file.  The format of enc-file is described in
              grops(1).  If not found in the current directory, the devps
              subdirectory of the default font directory is searched.

       -fname The internal name of the groff font is set to name.

       -in    Generate an italic correction for each character so that the
              character's width plus the character's italic correction is
              equal to n thousandths of an em plus the amount by which the
              right edge of the character's bounding box is to the right of
              the character's origin.  If this would result in a negative
              italic correction, use a zero italic correction instead.

              Also generate a subscript correction equal to the product of the
              tangent of the slant of the font and four fifths of the x-height
              of the font.  If this would result in a subscript correction
              greater than the italic correction, use a subscript correction
              equal to the italic correction instead.

              Also generate a left italic correction for each character equal
              to n thousandths of an em plus the amount by which the left edge
              of the character's bounding box is to the left of the
              character's origin.  The left italic correction may be negative
              unless option -m is given.

              This option is normally needed only with italic (or oblique)
              fonts.  The font files distributed with groff were created using
              an option of -i50 for italic fonts.

       -ooutput-file
              The output file is output-file instead of font.

       -k     Omit any kerning data from the groff font; use only for
              monospaced (constant-width) fonts.

       -m     Prevent negative left italic correction values.  Roman font
              files distributed with groff were created with -i0 -m to improve
              spacing with eqn(1).

       -n     Don't output a ligatures command for this font; use with
              monospaced (constant-width) fonts.

       -s     The font is special.  The effect of this option is to add the
              special command to the font file.

       -v     Print version and exit.

       -x     Don't use the built-in Adobe Glyph List.
