bosco commit 'Commit Message'
bosco commit -r <repoPattern> 'Commit Message'

This command is useful to commit batch updates across all of your repostories - use with care!

The typical use case here is if you want to make a small structural change across all of your services, you can quickly run through and make the change in each, then run this command, followed by bosco pushall to commit and then push all the changes up together with the same message.
