It adds nothing new to what the trivial and license wizard examples
show, other than a bunch of somewhat messy and outdated code to generate
C++ code files based on the input.
The example is referenced in a few parts of the documentation, but there
are equivalent snippets in the trivial and license wizard examples, so
point at those instead, and add some relevant API usage where needed.
Pick-to: 6.5
