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