[Info-mtools] [PATCH] Add support for lzip to lz/uz

[Antonio Diaz Diaz]

Hello,

Now that GNU tar has added direct support for lzip[1], it is perhaps 
time to offer the same capabilities to other platforms through the lz/uz 
commands.
[1] http://www.nongnu.org/lzip/lzip.html

The attached patch adds lzip support to lz/uz, fixes bzip2 support 
(.tb2), and documents the changes in the man pages for lz and uz.


Best regards,
Antonio.
