Revision file

Example Revision File

Below is an example of a revision file that gets generated by the liminal autogenerate command. This flow was heavily inspired by the Alembic migration workflow. When liminal upgrade is run, the operations in the upgrade() function are executed and when liminal downgrade is run, the operations in the downgrade() function are executed. Each revision is linearly linked to a previous revision, creating a timeline of revisions/operations. This allows for the user to traverse the history of their Benchling model.
