this file should contain a sequence of lines of the form

If a PostScript character is in the encoding to be used for the font
but is not mentioned in
will put it in the groff font file as an unnamed character,
which can be accessed by the
escape sequence in
R troff .
The groff font file will be output to a file called
R font .

These parameters are normally needed only for italic (or oblique) fonts.

Use this with constant-width fonts.
The font is special.
The effect of this option is to add the

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
option to give the font a smaller slant.
I -i n
Generate an italic correction for each character so that
the character's width plus the character's italic correction
is equal to
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
Also generate a left italic correction for each character
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
for italic fonts.
