-git drover is NOT IMPLEMENTED yet\&. See the EXAMPLE section for the equivalent sequence of commands to run\&.
+git drover applies a commit to a release branch\&. It creates a new workdir from an existing checkout to avoid downloading a new checkout without affecting the existing checkout\&. Creating a workdir requires symlinks so this does not work on Windows\&. See the EXAMPLE section for the equivalent sequence of commands to run\&.
