-# git-cl -- a git-command for integrating reviews on Rietveld
-# Copyright (C) 2008 Evan Martin <martine@danga.com>
-
-== Background
-Rietveld, also known as http://codereview.appspot.com, is a nice tool
-for code reviews.  You upload a patch (and some other data) and it lets
-others comment on your patch.
-
-For more on how this all works conceptually, please see README.codereview.
-The remainder of this document is the nuts and bolts of using git-cl.
-
-== Install
-Copy (symlink) it into your path somewhere, along with Rietveld
-upload.py.
-
-== Setup
-Run this from your git checkout and answer some questions:
-$ git cl config
-
-== How to use it
-Make a new branch.  Write some code.  Commit it locally.  Send it for
-review:
-$ git cl upload
-By default, it diffs against whatever branch the current branch is
-tracking (see "git checkout --track").  An optional last argument is
-passed to "git diff", allowing reviews against other heads.
-
-You'll be asked some questions, and the review issue number will be
-associated with your current git branch, so subsequent calls to upload
-will update that review rather than making a new one.
-
-== git-svn integration
-Review looks good?  Commit the code:
-$ git cl dcommit
-This does a git-svn dcommit, with a twist: all changes in the diff
-will be squashed into a single commit, and the description of the commit
-is taken directly from the Rietveld description.  This command also accepts
-arguments to "git diff", much like upload.
-Try "git cl dcommit --help" for more options.
-
-== Extra commands
-Print some status info:
-$ git cl status
-
-Edit the issue association on the current branch:
-$ git cl issue 1234
-
-Patch in a review:
-$ git cl patch <url to full patch>
-Try "git cl patch --help" for more options.
