That's only a sample gem done to show the Zorros people how to create a small gem.
It's only purpose is to add a tag to the git repository of a project each time it's deployed with capistrano. It heavily follows our way of working so it will probably not fit for you. But if it does, please, feel free to give us a hand with it!
How to use it
The gem supposes you've a multistage environment set up. You'll need to include
it on your
config/deploy/production.rb file, like that.
Once you've done it, you'll have a small task on capistrano wich will
automatically create a git tag with the format
dd-mm-yyyy each time you
deploy to production.
The tag will be created in your working copy's current branch, so make sure you're in the branch/commit you're deploying to tag the right thing.
