| - Create a remote branch named webkit-XYZ on https://github.com/USERNAME/%s.git repository based on the locally applied patch. |
| - USERNAME may be set using the environment variable GITHUB_USERNAME or as a command line option. It is then stored in git config as github.username. |
| - Github credential may be set using the environment variable GITHUB_TOKEN or as a command line option. (Please provide a valid GitHub 'Personal access token' with 'repo' as scope). It is then stored in git config as github.token. |

| - Clean the local Git repository |
| Notes: |
| - It is safer to provide a bug id using -b option (bug id from a git commit is not always working). |
| - As a dry run, one can start by running the script without -c. This will only create the branch on the user public GitHub repository. |
