SUMMARY="Database migration tool for SQLAlchemy"
DESCRIPTION="A database migrations tool written by the author of SQLAlchemy. \
It 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."
