// Driver for c++ extractor. Operates in two modes:
// - DEPS, scans build graph for active files and reports targets that need to
// be build for analyzing that file.
// - INPUTS, scans the source code for active files and returns all the sources
// required for analyzing that file.
//
// Uses stdin/stdout to take in requests and provide responses.
