+NAME
+----
+mftraining - feature training for Tesseract
+
+SYNOPSIS
+--------
+mftraining -U 'unicharset' -O 'lang.unicharset' 'FILE'...
+
+DESCRIPTION
+-----------
+mftraining takes a list of .tr files, from which it generates the
+files *inttemp* (the shape prototypes), *shapetable*, and *pffmtable*
+(the number of expected features for each character).  (A fourth file
+called Microfeat is also written by this program, but it is not used.)
+
+OPTIONS
+-------
+-U 'FILE'::
+	(Input) The unicharset generated by unicharset_extractor(1)
+
+-F 'font_properties_file'::
+	(Input) font properties file, each line is of the following form, where each field other than the font name is 0 or 1:
+
+	*font_name* *italic* *bold* *fixed_pitch* *serif* *fraktur*
+
+-X 'xheights_file'::
+	(Input) x heights file, each line is of the following form, where xheight is calculated as the pixel x height of a character drawn at 32pt on 300 dpi. [ That is, if base x height + ascenders + descenders = 133, how much is x height? ]
+
+	*font_name* *xheight*
+
+-D 'dir'::
+	Directory to write output files to.
+
+-O 'FILE'::
+	(Output) The output unicharset that will be given to combine_tessdata(1)
