+Alembic is a new database migrations tool, written by the author of
+SQLAlchemy. A migrations tool offers the following functionality:
+
+- Can emit ALTER statements to a database in order to change the structure of
+  tables and other constructs
+- Provides a system whereby "migration scripts" may be constructed; each
+  script indicates a particular series of steps that can "upgrade" a target
+  database to a new version, and optionally a series of steps that can
+  "downgrade" similarly, doing the same steps in reverse.
+- Allows the scripts to execute in some sequential manner.
