Run different post-commit hook script based on change

Is there a way to trigger different scripts to run from the post-commit hook
based on what was changed?

I have two scenarios:
1) When a commit happens on a branch I want the changes to be automatically
deployed to server a, but when a commit happens to the trunk I want the
changes to be automatically deployed to server b.
2) When a commit happens that involves changes to the web directory only, I
want server a to be automatically updated without a build, but when changes
happen to any other directory or file outside of web, i want a full build to
occur for server a.

I have builds and updates working from my post-commit hook, all I am looking
for is help on knowing what has changed so I can trigger the correct script
to run.

Does anyone know how to do this, or if this capability even exists?
