7.7 Reporting configuration information

On platforms that support it, the coNCePTuaL run-time library is also an executable program that can be run from the command line. Executing the library outputs to the standard output device a complete log-file prologue and epilogue but no data.¹⁹ This feature makes it quite convenient to determine all of the configuration options, compiler features, etc. that were used to build the run-time library.
