FilePrinter

Imports that exist only to configure this generator.

Dropped from the embedded descriptor, so generated code never drags the generator's own option classes onto a consumer's classpath.

protobuf-java's descriptor accessor for each file it has compiled in.

Needed because a generated file object cannot be produced for these - protobuf-java owns them - and FileDescriptor.buildFrom insists on the real dependency objects rather than fresh copies, which would not be eq to the ones a Well-Known Type's own classes carry.
