 Ideas on setting up a Horde Git repository

 ++ Description
+This project is to determine what the next generation of the Horde will use
to store and organize source code.
+Some initial work has been done with Git and SVN conversions of the current
CVS repository.

-+++ Setup
+++ Requirements
++++ Must-haves
+* Offline review of local changes
+* Ability to hook into Wicked for ticket updates from commit messages
+
++++ Nice-to-haves
+* Submodule support
+> Today checking out a Horde app within an existing Horde checkout works
fine.  This includes making single-commit changes across applications.
+* Browseable by Chora
+> Naturally no matter what we choose Chora support will either be added or
will improve.  However if it is already supported by Chora all the better.

+++ The Contenders
+> In alphabetical order...

++++ Bazaar

These likely can be reused for other SCM systems as well.

The repository size is indeed much larger.  In addition submodule support
(as we use it today) has not been proven to the satisfaction of the
developers.
