Egg is an Emacs interface to git. It's a suite composed of a minor-mode and various special-buffers presenting different UIs to help the user performing many git operations.

• egg-minor-mode: providing git-specific vc-look-alike interface including similar key-bindings, a minor-mode menu and history annotations (blame).
• egg's status-buffer:
  • index manipulation/commit preparation
  • interactive rebase stepping
  • merge conflict resolution
  • stashing work-in-progress
  • adding ignore pattern
  • staging new files
  • ediff or ediff3 launching. (e.g. 3-way ediff of work-dir/INDEX/HEAD, 3-way ediff of work-dir/theirs/ours)
• egg's log-buffer
  • browse repo's history and reflogs
  • ref (tag, branch, etc) creation and deletion
  • push and fetch
  • start merge/rebase/interactive-rebase session
  • anchor HEAD (reset)
  • search history (pickaxe), grep commit message.
  • compare revisions
• egg's file-log-buffer: restricted version of the log-buffer, used to browse history of a single file.
• egg's query:commit-buffer: restricted variation of the log-buffer, used to browse history-search's results (pickaxe or message grep)
• egg-grep: a compile-mode which can grep files in non-checkout git revisions.
• egg's commit-log-edit buffer: used to compose the commit-message for the upcoming commit. it can do some minor index manipulation. gpg-signature can also be enabled.
• egg's tag:msg-buffer: used to compose the message of an annotated tag. gpg-signature can also be enabled.
• egg's diff-buffer: used to view the delta between file or repo revisions.

The design of the status-buffer Egg was borrowed/stolen from Magit. Egg, however has much more functionalities than the status buffer.

Magit is an interface to the version control system Git, implemented by Marius Voller. His code at: http://philjackson.github.com/magit/
