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