Log:
Remove buggy example code from the documentation

Instead point readers to the latest, correct example code in SVN until we find
a way to automatically include example sources into the documentation (or until
someone steps up to maintain these actively).

This ensures that the examples are up-to-date, buildable, and most of all that
readers don't pick up incorrect usage.
