// raw source files --(metalava)--> stub source files --(javac)--> stub jar files
//
// The metalava conversion is done by droidstub modules *-api-stubs-docs.
// The javac compilation is done by java_library modules android_*_stubs_current.
// The metalava conversion is also responsible for creating API signature files
// and comparing them against the last API signature in api/*-current.txt files
// and also against the latest frozen API signature in prebuilts/sdk/*/*/api/android.txt
// files.
