I have a few forked repo’s, either because I needed to make some unique and custom change to the project or because I wanted a safe snapshot in time of the project.
Occasionally I’d like to update these forks against their master and the Google has provided a very concise blog post here(http://bradlyfeeley.com/2008/09/03/update-a-github-fork-from-the-original-repo/). Kudo’s to Bradly Feeley.
