Another way to use skip is for a lazy checkout. This makes mr skip
operating on a repo unless it already exists. To enable the
-repo, you have to explicitly check it out (using "mr -d foo checkout").

When looking for a command to run for a given action, mr first looks for
a parameter with the same name as the action. If that is not found, it
looks for a parameter named "VCS_action" (substituting in the name of the
-version control system and the action). The name of the version control
-system is itself determined by running each defined "VCS_test" action,

Internally, mr has settings for "git_update", "svn_update", etc. To change
the action that is performed for a given version control system, you can
to the existing value of the parameter. In this way, actions
can be constructed accumulatively.
