+SHAPECLUSTERING(1)
+==================
+:doctype: manpage
+
+NAME
+----
+shapeclustering - shape clustering training for Tesseract
+
+SYNOPSIS
+--------
+shapeclustering -D 'output_dir'
+    -U 'unicharset' -O 'mfunicharset'
+    -F 'font_props' -X 'xheights'
+    'FILE'...
+
+DESCRIPTION
+-----------
+shapeclustering(1) takes extracted feature .tr files (generated by
+tesseract(1) run in a special mode from box files) and produces a
+file *shapetable* and an enhanced unicharset.  This program is still
+experimental, and is not required (yet) for training Tesseract.
+
+OPTIONS
+-------
+-U 'FILE'::
+	The unicharset generated by unicharset_extractor(1).
+
+-D 'dir'::
+	Directory to write output files to.
+
+-F 'font_properties_file'::
+	(Input) font properties file, where 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'
+
+-O 'FILE'::
+	The output unicharset that will be given to combine_tessdata(1).
