+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 included by reference in Adobe's PDF version 1.4 and later.
+
+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.
