+    (description
+     "Zutils is a collection of utilities able to process any combination of
+compressed and uncompressed files transparently.  If any given file, including
+standard input, is compressed, its decompressed content is used instead.
+
+@command{zcat}, @command{zcmp}, @command{zdiff}, and @command{zgrep} are
+improved replacements for the shell scripts provided by GNU gzip.
+@command{ztest} tests the integrity of supported compressed files.
+@command{zupdate} recompresses files with lzip, similar to gzip's
+@command{znew}.
+
+Supported compression formats are bzip2, gzip, lzip, and xz.  Zutils uses
+external compressors: the compressor to be used for each format is configurable
+at run time, and must be installed separately.")
