%global _description\
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.\
\
Documentation and status of Alembic is at http://readthedocs.org/docs/alembic/
