+JBIG-KIT implements a highly effective data compression algorithm for
+bi-level high-resolution images such as fax pages or scanned
+documents.
+
+JBIG-KIT provides a portable library of compression and decompression
+functions with a documented interface that you can very easily include
+into your image or document processing software. In addition, JBIG-KIT
+provides ready-to-use compression and decompression programs with a
+simple command line interface (similar to the converters found in Jef
+Poskanzer's PBM graphics file conversion package).
+
+JBIG-KIT implements the specification
+
+ International Standard ISO/IEC 11544:1993 and ITU-T Recommendation
+ T.82(1993), "Information technology - Coded representation of picture
+ and audio information - progressive bi-level image compression",
+ <http://www.itu.ch/itudoc/itu-t/rec/t/t82_23822.html>,
+
+which is commonly referred to as the "JBIG standard". JBIG (Joint
+Bi-level Image experts Group) is the committee which developed this
+international standard for the lossless compression of images using
+arithmetic coding. Like the well-known compression algorithms JPEG and
+MPEG, also JBIG has been developed and published by the International
+Organization for Standardization (ISO) and the International
+Telecommunication Union (ITU) (see also <http://www.iso.ch/> and
+<http://www.itu.ch/>).
