using ruby to checkout a tag in git?

I want to write a ruby script that is a command line tool that takes a tag ID as a parameter and then runs the equivalent of "git checkout tag_id". I would then use rsync to push the checked out directory to servers. I've looked at the rugged gem and the git gem, but they seem to interact with git in a way that isn't intuitive in doing something like this. Should I just use the system call or is there a more ruby way to do what I'm trying to do?

I have /User/git_repo cloned from say [email protected]/company/this_repo.git. Manually I would "git fetch --tags" and then "git checkout tag_id". I would want to then rsync the result over to the servers.

There's the ruby-git gem - install it with $ gem install git. It handles the system command line calls - here's an example for Ruby >= 1.9:

require 'git'

g = Git.init
       Git.init('project')
       Git.init('/home/schacon/proj',
        { :repository => '/opt/git/proj.git',
           :index => '/tmp/index'} )

g.fetch

g.checkout('tag_id')

You can get an array of tags from g.tags. I'd use this over writing my own system calls, as this repo seems to be currently maintained (last commit two days ago).
