A little Go command-line program that manages a list of git repos and runs git commands on all repos.

This program supports the article: Let's Go: Command-line Programs with Golang.

It accepts two command-line arguments:

• --command : the git command (wrap in double quotes for multi-arguments commands)
• --ignore-errors: keeps going through the list of repos even the git command failed on some of them

The list of repos is controlled by two the environment variables:

• MG_ROOT : the path to a root directory that contains all the repos
• MG_REPOS : the names of all managed repos under MG_ROOT
