NAME
          afmtodit - create font files for use with groff -Tps

     SYNOPSIS
          afmtodit [ -ns ] [ -ddesc_file ] [ -eenc_file ] [ -in ] [
          -an ] afm_file map_file font

     DESCRIPTION
          afmtodit creates a font file for use with groff and grops.
          afmtodit is written in perl; you must have perl version 3
          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.
          font is the groff name of the font.  If a PostScript
          character is in the encoding to be used for the font but is
          not mentioned in map_file then afmtodit will put it in the
          groff font file as an unnamed character, which can be
          accessed by the \N escape sequence in troff.  The groff font
          file will be output to a file called font.

          If there is a downloadable font file for the font, it may be
          listed in the file
          /usr/products/src2/gcc/AIX.d/lib/groff/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 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
          -n   Don't output a ligatures command for this font.  Use
               this with constant-width fonts.

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

          -ddesc_file
               The device description file is desc_file rather than
               the default DESC.

          -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).

          -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.

          -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 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.

               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.
