release-state-fn.sh
This is the main version and state update logic... you could say that it's the innermost engine for the release mechanism. It tries to be agnostic of versioning schemes, and relies on release-version-fn.sh to supply necessary functions that are specific for versioning schemes.
release-version-fn.sh
Supplies functions that are specific to versioning schemes:
