This tool takes a sequence of Protobuf files that claim to conform to the GTFS-RT specification, performs a validation pass on it, and reports violations.

Errors are divided into within-file violations and between-file violations. Within-file violations occur wherever the file does not conform to the spec. Examples include file corruption, missing fields, and missing structs. Between-file violations occur wherever there are unexpected changes between files. Examples include trains going backwards or disappearing from the feed.
