Hi all,

[Please CC me in reply, I am not subscribed]

I would like to be only using git on my local systems but there are
other folks out there who prefer to use different VCS systems.

In addition there are VCS-like data storage systems (such as Mediawiki)
and general data storage/transfer systems where one might want to track
changes using git (such as LDAP and rsync).

I still need mostly bi-directional interoperability between git and
CVS, Subversion, Mercurial, Breezy/Bazaar, Darcs, Mediawiki and rsync.
On the horizon are Fossil and Pijul but I probably won't need those any
time soon. Recently I had a situation where GNU Arch support would have
been helpful for viewing historical commit information but I assumed
that support for it didn't exist so I didn't bother.

Is there a location in the git documentation for pointers to software
(such as git-remote-* helpers) that can help with VCS interoperability?

Is there a place for people interested in VCS interoperability software
to collaboratively maintain them?

Should the VCS interop software in the git git repo move there?

I'm currently using the following tools:

CVS: https://github.com/osamuaoki/git-cvs (slightly better than git-cvsimport)
Subversion: git-svn (not using a git-remote-* workflow)
Mercurial: git-remote-hg (there are lots of forks/implementations)
Breezy/Bazaar: git-remote-bzr (there are lots of forks)
Darcs: nothing as only fast-export/fast-import seems possible
Mediawiki: https://github.com/Git-Mediawiki/Git-Mediawiki
rsync: manually rsyncing and importing commits

What other tools are folks using?

Any other thoughts on this?

I don't know if you need it to be bidirectional, but there is
git-archimport. I'll warn you that it's pretty unmaintained, though so
best of luck. :)

There's:

  https://git.wiki.kernel.org/index.php/Interfaces,_frontends,_and_tools#Interaction_with_other_Revision_Control_Systems

I have no idea how up-to-date it is (I admit that I converted all of my
repos to Git in 2006 and haven't really looked back).

I haven't used it, but there's also:

  https://github.com/glandium/git-cinnabar

which seems to be actively used and maintained.

It seems to miss a number of tools, I've requested an account and will
update it with the tools I know about. Thanks for all the pointers.
