Yoyo is a database schema migration tool. You write database migrations
as Python scripts containing raw SQL statements or Python functions.
Installation:
------------
```
pip install yoyo-database-migrations
```

What does yoyo-migrations do?
-----------------------------
As your database application evolves, changes to the database schema may be
required. Yoyo lets you write migration scripts in Python containing
SQL statements to migrate your database schema to a new version.
A simple migration script looks like this:
```python
# file: migrations/0001.create-foo.py
from yoyo import step
step(
"CREATE TABLE foo (id INT, bar VARCHAR(20), PRIMARY KEY (id))",
"DROP TABLE foo",
)
```
Yoyo manages these database migration scripts,
gives you command line tools to apply and rollback migrations,
and manages dependencies between migrations.
Database support
----------------
PostgreSQL, MySQL and SQLite databases are supported.
ODBC and Oracle database backends are available (but unsupported).
Improvements
------------
* Command `yoyo showmigrations` added
