Fabric is great for running commands. But what a lot of programmers do not realize is that deployment is a process. That process involves running automated tests, packaging all of the assets, using package managers to upgrade/downgrade based on versioned release schemes, database migration, post-upgrade scripts, and quick/painless rollback (downgrade) if there's a major blocking bug for users.
