move to git

[Ralf Wildenhues]

Hello libtool list readers,

GNU Libtool's primary source repository is now managed with git:
<http://savannah.gnu.org/git/?group=libtool>

Note that there were several conversions, so the current repo has been
rewound and is not a continuation of the earlier, read-only git repo.

Please do not continue to use the CVS repo.  Its contents will soon be
replaced with a single file pointing to the git one.

Thanks to Jim Meyering for all the help with this, and thanks to
everyone who tried out earlier versions and reported issues with it!

Cheers,
Ralf
