SQL::PatchDAG This module manages a directory containing SQL files that must be run in a particular order. This order is specified implicitly by the contents of the files: each of them must contain a dependency declaration, which the module provides code to help maintain. This provides a merge-friendly way to introduce schema patches in a code base across multiple branches. Patch application itself is up the caller. The module does not talk to a database.
