SigTest - checks your api is still backward compatible and highlights additions

sigtest: SigTest
The Signature Test tool makes it easy to compare the signatures of two different implementations or different versions of the same API. When it compares different implementations of the same API, the tool verifies that all of the members are present, reports when new members are added, and checks the specified behavior of each API member. When it compares different versions of the same API, the tool checks that the old version can be replaced by the new one without adversely affecting existing clients of the API.
