If "file -bizL" does not return a supported type. Check if the dist file
is recognized by bsdtar and if yes extract from it.

bsdtar can recognize many containers and compression algorithms.

lzma is the best compression the GNU guys are using in their dist files.

% file -bizL wget-1.12.tar.lzma
application/octet-stream; charset=binary

"file" output is not really useful.

Using lzma can reduce the size of source packages by a good margin.
