// Ancillary binary to exercise `megafine --region` (C++ version).
//
// Takes three sleep durations (seconds) and brackets the middle one with the
// region markers, so `megafine --region` should report ~ the 2nd value:
//
//     sleep(before); megafine_start(); sleep(region); megafine_stop(); sleep(after);
//
// Usage: megafine-region-cpp <before> <region> <after>
//
//     g++ -O2 -Iinstrument instrument/megafine-region-cpp.cpp -o megafine-region-cpp
