+# The Plugin::Migrator class contains the logic to run migrations from
+# within plugin directories. The directory in which a plugin's migrations
+# should be is determined by the Plugin#migration_directory method.
+#
+# To migrate a plugin, you can simple call the migrate method (Plugin#migrate)
+# with the version number that plugin should be at. The plugin's migrations
+# will then be used to migrate up (or down) to the given version.
