 Dependencies also work in reverse; South knows not to undo that 0003_user_profile migration until it has undone the 0002_post migration.
+
+You can have multiple dependencies, and all sorts of wacky structures; there are, however, two rules:
+
+ - No circular dependencies (two or more migrations depending on each other)
+ - No upwards dependencies in the same app (so you can't make 0002_post in the forum app depend on 0003_room in the same app, either directly or through a dependency chain.
