router.run('migration_name')

router.run()

Migration files
By default, migration files are looked up in os.getcwd()/migrations directory, but custom directory can be given.
Migration files are sorted and applied in ascending order per their filename.
Each migration file must specify migrate() function and may specify rollback() function:
def migrate(migrator, database, fake=False, **kwargs):
pass

def rollback(migrator, database, fake=False, **kwargs):
pass
