This library provides a means for Component Resolvers serving the fuchsia.component.resolution.Resolver protocol to read and parse a fuchsia.version.AbiRevision value from a package directory proxy.
The Component Resolver may include the parsed result in the fuchsia.component.resolution.Component returned to Component Manager.
The abi revision is read from the AbiRevision::PATH established by RFC-0135 and defined in the version-history library.
