# An example of how to add a new revision control system type to mr.
# git fake bare repositories have a detached workspace. One potential
# application is storing dotfiles in git, keeping them checked out in
-# one $HOME, but checked into different git repositories. This file adds
+# ones $HOME, but checked into different git repositories. This file adds
# support for them, separate from the normal git support.
# To make mr use this file, add a line like this inside the [DEFAULT]
# And an example repo using it would look something like:
#[.dotfiles]
