|
.SH "DESCRIPTION"
|
|
.sp
|
|
mftraining takes a list of \&.tr files, from which it generates the files \fBinttemp\fR (the shape prototypes), \fBshapetable\fR, and \fBpffmtable\fR (the number of expected features for each character)\&. (A fourth file called Microfeat is also written by this program, but it is not used\&.)

\-F \fIfont_properties_file\fR
|
|
.RS 4
|
