From the top of the git-cola repository a release can then be created by running:
Meta/release --all
This branch is intended to be checked out in a seperate repository within a git-cola repository, e.g. at git-cola/Meta (and is the reason that git-cola's .gitignore mentions "Meta". The release script assumes that you have a clone of git-cola.github.com sibling to the git-cola repository. Your directory structure should look roughly like this:
$HOME/src/git-cola
$HOME/src/git-cola.github.com
"$HOME/src" can be any arbitrary directory.
