NAME
     tfmtodit - create font files for use with groff -Tdvi

SYNOPSIS
     tfmtodit [ -sv ] [ -ggf_file ] [ -kskewchar ] tfm_file
              map_file font

     It is possible to have whitespace  between  a  command  line
     option and its parameter.

DESCRIPTION
     tfmtodit creates a font  file  for  use  with  groff  -Tdvi.
     tfm_file  is  the  name  of the TeX font metric file for the
     font.  map_file is a file giving the groff names for charac-
     ters  in the font; this file should consist of a sequence of
     lines of the form:

          n c1 c2 ...

     where n is a decimal integer  giving  the  position  of  the
     character  in  the font, and c1, c2,...  are the groff names
     of the character.  If a character has  no  groff  names  but
     exists  in  the  tfm  file, then it will be put in the groff
     font file as an unnamed character.  font is the name of  the
     groff font file.  The groff font file is written to font.

     The -s option should be given if the font is special (a font
     is special if troff should search it whenever a character is
     not found in the current font.)  If the font is special,  it
     should  be  listed in the fonts command in the DESC file; if
     it is not special, there is no need to list it, since  troff
     can automatically mount it when it's first used.

     To do a good job of math typesetting,  groff  requires  font
     metric  information not present in the tfm file.  The reason
     for this is that TeX has separate math italic fonts  whereas
     groff  uses  normal  italic  fonts for math.  The additional
     information required by groff is given by the two  arguments
     to  the math_fit macro in the Metafont programs for the Com-
     puter Modern fonts.  In  a  text  font  (a  font  for  which
     math_fitting  is false), Metafont normally ignores these two
     arguments.  Metafont can be made to put this information  in
     the gf file by loading the following definition after cmbase
     when creating cm.base:


          def ignore_math_fit(expr left_adjustment,right_adjustment) =
              special "adjustment";
              numspecial left_adjustment*16/designsize;
              numspecial right_adjustment*16/designsize;
              enddef;

     For the EC font family, load the following definition  after
     exbase (it is probably easiest to patch exbase.mf locally):


          def ignore_math_fit(expr left_adjustment,right_adjustment) =
              ori_special "adjustment";
              ori_numspecial left_adjustment*16/designsize;
              ori_numspecial right_adjustment*16/designsize;
              enddef;

     The gf file created using this modified  cm.base  or  exbase
     should  be  specified  with  the  -g  option.  The -g option
     should not be given for a font  for  which  math_fitting  is
     true.

OPTIONS
     -v   Print the version number.

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

     -kn  The skewchar of this font is at position n.   n  should
          be  an  integer;  it may be given in decimal, or with a
          leading 0 in octal, or with a  leading  0x  in  hexade-
          cimal.   The  effect  of  this  option is to ignore any
          kerns whose second component is the  specified  charac-
          ter.

     -ggf_file
          gf_file is a gf file produced  by  Metafont  containing
          special  and numspecial commands giving additional font
          metric information.
