As a follow-up to our branching and tag name changes announcement, we've now established the formal structure for Drupal.org's Git repositories! Instead of having projects sub-divided as /drupal, /contributions/modules, /contributions/themes, and so on as we currently do at http://cvs.drupal.org/, projects are now located in the "root" namespace (all in the same top-level directory). This more accurately reflects how Drupal behaves, since a module and theme can't have the same name (this causes all kinds of wacky fun since 'help' is both a theme function and a hook), and also matches our project shortname/URL conventions (http://drupal.org/project/foo).
To see this in action, head over to http://git.drupal.org/.

Oddness of projects vs project
This is all great. It's odd that on Drupal.org views is /project/views and on git.drupal.org views is /projects/views.
It may be that we should synchronize those. Think of all the 404s that will ensue due to the difference. Are 404s like killed kittens?
Hrm. Fair point.
I guess if we are going to change this, now would be the time to do it before too many people are using git.drupal.org actively.
Could you open an issue tagged 'git phase 2' to discuss it?
Opened issue
