GitHub set author/committer

I've been working with Git lately and more specifically GitHub. I noticed something odd one day. Where most commits have one author listed, these commits had both a author and a committer listed.

More specifically, the author field was the two members of the pair and the committer name was the workstation they were working on.

Example:

After playing around with it for a while, I figured out how to do it. Within a git project clone, run the following commands.

1) git config user.name = 'Workstation Perlwizard'
2) git config user.email = 'devs2@perlwizard.org'
3) export GIT_AUTHOR_NAME='Bob Smith and Betty Jones'
4) export GIT_AUTHOR_EMAIL='devs@perlwizard.org'

Both of the email addresses need to be addresses Github doesn't know about (i.e. not used to sign up for an account).

I could see using this while pairing with someone so you both get name credit for your commits.
