// How stubs are generated:

// raw source files --(metalava)--> stub source files --(javac)--> stub jar files
//
// - The metalava conversion is done by droidstub modules
// - The javac compilation is done by java_library modules
//
// The metalava conversion is also responsible for creating API signature files
// and comparing them against the checked in API signature, and also checking compatibility
// with the latest frozen API signature.
