 The CMake tutorial provides a step-by-step guide that covers common build
 system issues that CMake helps address. Seeing how various topics all
-work together in an example project can be very helpful. The tutorial
-documentation and source code for examples can be found in the
-``Help/guide/tutorial`` directory of the CMake source code tree. Each step has
-its own subdirectory containing code that may be used as a starting point. The
-tutorial examples are progressive so that each step provides the complete
