+OCRopus is a state-of-the-art document analysis and OCR system, featuring 
+pluggable layout analysis, pluggable character recognition, statistical 
+natural language modeling, and multi-lingual capabilities.
+
+The system is being developed with the generous support from Google and 
+other organizations; the primary developers are at the IUPR Research 
+Group at the DFKI Research Center.
+
+This requires tesseract and iulib.

+.TH ocroscript 1 "June 06, 2008"
+.SH NAME
+ocropus \- command line OCR tool
+.SH SYNOPSIS
+.B ocroscript
+.RI "<script> <arguments>"
+.SH DESCRIPTION
+You can see a list of all available commands by looking in the $OCROSCRIPTS
+(/usr/share/ocropus/scripts/ by default) path.
+.PP
+The \(oqrecognize\(cq script uses tesseract for recognition and sends the html-based hOCR
+ouput to stdout. Tesseract is probably the most mature text recognizer within
+OCRopus at the moment. Natively, Tesseract doesn't do layout analysis, but
+combined with OCRopus, it makes for a pretty good OCR system:
+.RS
+$ ocroscript recognize page.png > page.html
+.RE
+.PP
+Here is a brief summary of the remaining command line commands available.
+You will need to look at the script to see what the command line arguments are:
+.TP
+degrade.lua
+Simple document image degradation
+.TP
+hocr-to-text.lua
+Convert hOCR output to plain text.
+.TP
+line-clean.lua
+Given a line image, remove marginal noise and fix some other problems.
+.TP
+sauvola.lua
+Perform Sauvola thresholding.
+.SH SEE ALSO

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
