+"""BUMP is a semantic versioning bump script which accepts the following

+   -m - a "major" version bump equal to +1.0.0
+   -n - a "minor" version bump equal to +0.1.0
+   -p - a "patch" version bump equal to +0.0.1
+
+   All of these options allow for the -r flag, which indicates that the state
+   is a RELEASE not a SNAPSHOT. If -r is not specified, then -SNAPSHOT is
+   appended to the updated version string."""
