+.SH NAME
+xlunzip \- test tool for the lzip_decompress linux module
+.SH SYNOPSIS
+.B xlunzip
+[\fI\,options\/\fR] [\fI\,files\/\fR]
+.SH DESCRIPTION
+Xlunzip is a test tool for the lzip decompression code of my lzip patch for
+linux. Xlunzip is similar to lunzip, but it uses the lzip_decompress linux
+module as a backend. Xlunzip tests the module for stream, buffer\-to\-buffer,
+and mixed decompression modes, including in\-place decompression (using the
+same buffer for input and output). You can use xlunzip to verify that the
+module produces correct results when decompressing single member files,
+multimember files, or the concatenation of two or more compressed files.
+Xlunzip can be used with unzcrash to test the robustness of the module to
+the decompression of corrupted data.
+.PP
+The distributed index feature of the lzip format allows xlunzip to
+decompress concatenated files in place. This can't be guaranteed to work
+with formats like gzip or bzip2 because they can't detect whether a high
+compression ratio in the first members of the multimember data is being
+masked by a low compression ratio in the last members.

+.TP
+\fB\-\-nofill\fR
+do not pass a fill function; requires \fB\-\-insize\fR
+.TP
+\fB\-\-noflush\fR
+do not pass a flush function; requires \fB\-\-outsize\fR
+.PP
+If no file names are given, or if a file is '\-', xlunzip decompresses
+from standard input to standard output.
+Numbers may be followed by a multiplier: k = kB = 10^3 = 1000,
+Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...
+.PP
+To extract all the files from archive 'foo.tar.lz', use the commands
+\&'tar \fB\-xf\fR foo.tar.lz' or 'xlunzip \fB\-cd\fR foo.tar.lz | tar \fB\-xf\fR \-'.
+.PP
+Exit status: 0 for a normal exit, 1 for environmental problems (file
+not found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
+invalid input file, 3 for an internal consistency error (eg, bug) which
+caused xlunzip to panic.
