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 check that the

module produces correct results when decompressing single member files,

multimember files, or the concatenation of two or more compressed files.

module as a backend. Xlunzip tests the module for stream, buffer\-to\-buffer,
