See JekyllPublisher.py --help for more information on usage.

You can create new pages, new blog posts, and commit/publish your changes to GitHub Pages using this program. It will automatically insert the current date and other correct front matter for blog posts and pages, saving you the trouble of having to remember how it's all laid out.

Personally I have renamed the file to pub and stuck it in /usr/local/bin. It will work correctly regardless of where the script file is stored, but your working directory must be the root of your Jekyll project.
