-jbig2dec is a decoder library and example utility implementing the JBIG2 bi-level image compression spec.
+jbig2dec is a decoder library and example utility implementing the JBIG2 bi-level image
+compression spec. Also known as ITU T.88 and ISO IEC 14492, and now included by reference in
+Adobe's PDF 1.4.
+
+The basic invocation is:
+
+ jbig2dec [-o <output file>] file.jbig2
+
+It also supports separate 'global' and 'page' streams, generally extracted from some embedded
+format:
+ jbig2dec [-o <output file>] <global_stream> <page_stream>
+
+The program is only partially functional at this time, but should be useful in some limited
+contexts. We welcome files that the decoder can't handle, or renders incorrectly.
+
+A set of example files is available from http://www.ece.ubc.ca/spmg/jbig2/bitstreams/main.html
