* update build instructions Usage of "modern" CMake syntax and using specific out of source build. Further add example on how to build in parallel, build a specific target and how to change the compiler. This closes #3236.
This made language statistics look much more skewed towards Perl than they should be.
- Hooks should be disabled for all tests.
- Added 'performance' make target that constructs an 8,000+ task database and runs benchmark queries against it.
