I can't take full credit for crafting this. It came up in discussions in the comments on GitHub for migrating Twitter Bootstrap to the MIT License. Basically, it extracts unique email addresses for all commit authors in a Git repository:

git log --pretty=format:"%aE" | sort | uniq

For a more personable list, you can prepend each author's name as well:

git log --pretty=format:"%aN <%aE>" | sort | uniq

Running either of those on a popular repository gives you an idea of the enormous collaboration that takes place in open-source projects.

Awesome, right? It's one of those things that make me realize I'm probably not taking full advantage of the tools that I use on a daily basis.
