+/**
+ * Defines an interface for a class which can update a Drupal project.
+ *
+ * An Updater currently serves the following purposes:
+ *   - It can take a given directory, and determine if it can operate on it.
+ *   - It can move the contents of that directory into the appropriate place
+ *     on the system using FileTransfer classes.
+ *   - It can return a list of "next steps" after an update or install.
+ *   - In the future, it will most likely perform some of those steps as well.
