Subject: [PATCH] This framework builds the 'minigzip' sample program supplied
 with libz.  It is a non-GPL-polluted minimal implementation of the 'gzip'
 command, yielding a 12k executable (vs ~100k for gzip).

+.Sh NAME
+.Nm minigzip
+.Nd minimal implementation of the 'gzip' compression tool
+.Sh SYNOPSIS
+.Nm minigzip
+.Op Fl d
+.Op Ar file ...
+.Sh DESCRIPTION
+.Nm
+is a minimal implementation of the gzip utility.  It supports
+compression and decompression of individual files, as well as
+streaming compression and decompression via standard input and
+output.
+.Pp
+The default operation is compression, decompression can be 
+selected by supplying the
+.Fl d
+flag on the commandline.
+.Pp
+If any
+.Ar file
+arguments are supplied, the operation is performed on each file 
+separately.  Compression replaces the original file with one having a
+.Pa .gz
+suffix.  Decompression will remove a
+.Pa .gz
+suffix if one is present.
+.Pp
+If no
+.Ar file
+arguments are supplied,
+.Nm
+reads from standard input and writes the results of the operation 
+to standard output.
+.Sh AUTHORS
+.Nm
+was written by Jean-loup Gailly.
