 718      "JBIG-KIT implements the JBIG1 data compression standard (ITU-T T.82 and
 719 ISO/IEC 11544:1993), designed for bi-level (one bit per pixel) images such as
 720 black-and-white scanned documents.  It is widely used in fax products, printer
 721 firmware and drivers, document management systems, and imaging software.
 722
 723 This package provides a static C library of (de)compression functions and some
 724 simple command-line converters similar to those provided by netpbm.
 725
 726 Two JBIG1 variants are available.  One (@file{jbig.c}) implements nearly all
 727 options of the standard but has to keep the full uncompressed image in memory.
 728 The other (@file{jbig85.c}) implements just the ITU-T T.85 profile, with
 729 memory management optimized for embedded and fax applications.  It buffers
 730 only a few lines of the uncompressed image in memory and is able to stream
 731 images of initially unknown height.")
