.SH DESCRIPTION
.IR Tfm2difont (1)
converts tfm files to ditroff compatible width tables which can subsequently
be run through 
.I makedev
and used with ditroff.
A file is created with the same name as the tfm file with the `.tfm' extension
removed.
The `name' and `internalname' are set to the same name as the font.
.PP
The 
.B -s 
flag causes the font(s) to be considered special.
The
.B -w
flag allows you to set
.I spacewidth.
Normally, a non-special font is assumed to have the ligatures
.BR ff ,
.BR fi ,
.BR fl ,
.B ffi
and
.BR ffl .
The 
.B -l
flag causes a named ligature to be removed.
Any number of 
.B -l
flags may be given.
Ligatures are ignored if the font is special since special fonts don't have
ligatures.
Because the `a' character is used for kerning information in non-special
fonts, it must exist in a non-special font.
.PP
The created width table contains the size of the characters at 10 points 
.RI ( unitwidth
in the DESC file).
.IR Troff (1)
scales the width of characters depending on the size currently in use.
So, if a 5 point font is being used, the width is halved.
Because of this, you cannot create a separate font with reshaped characters
for five points with 
METAFONT.
\*(TX allows you to do this though.
