Pushing/pulling a specific branch between local and remote repository

from http://www.mariopareja.com/blog/archive/2010/01/11/how-to-push-a-new-local-branch-to-a-remote.aspx : 

git push -u origin plugin
 
This tells git to push changes from your plugin branch to the plugin branch on the origin repository. If origin does not have a plugin branch, it is created on the fly. The -u tells git that you want to be able to easily push and pull changes to that branch in the future.

 To perform the opposite, to pull a repo other than master,  use:

git checkout -b experimental origin/experimental
