// This header declares a family of `ABSL_LOG` macros as alternative spellings
// for macros in `log.h`.
//
// Basic invocation looks like this:
//
//   ABSL_LOG(INFO) << "Found " << num_cookies << " cookies";
//
// Most `ABSL_LOG` macros take a severity level argument. The severity levels
// are `INFO`, `WARNING`, `ERROR`, and `FATAL`.
//
// For full documentation, see comments in `log.h`, which includes full
// reference documentation on use of the equivalent `LOG` macro and has an
// identical set of macros without the ABSL_* prefix.
