+// 000-CatchMain.cpp
+
+// In a Catch project with multiple files, dedicate one file to compile the
+// source code of Catch itself and reuse the resulting object file for linking.
+
+// Let Catch provide main():
+#define CATCH_CONFIG_MAIN
+
+#include <catch2/catch.hpp>
+
+// That's it
+
+// Compile implementation of Catch for use with files that do contain tests:
+// - g++ -std=c++11 -Wall -I$(CATCH_SINGLE_INCLUDE) -c 000-CatchMain.cpp
+// - cl -EHsc -I%CATCH_SINGLE_INCLUDE% -c 000-CatchMain.cpp
