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

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 Computer 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;
