Some git commands

To see all availabe branches (similar to available mercurial queues): git branch
To make a new branch: git branch branch_name
To go to a specific branch: git checkout branch_name

To add changes to a github pull request:
git add . (git add --all also removes entries when there are removed files)
git commit -m "your commit message"
git push https://github.com/mwargers/gaia.git branch_name

To see changed files between master and your branch:
git diff --name-status master..branch_name

To remove file from git: git rm file_name

How to prevent pushing changes to master (at least without warning):

git config push.default nothing
