*
* The main differences between this generator and the UnixMakefile
* generator family are:
* - We don't care about VERBOSE variable or RULE_MESSAGES property since
* it is handle by Ninja's -v option.
* - We don't care about computing any progress status since Ninja manages
* it itself.
* - We don't care about generating a clean target since Ninja already have
* a clean tool.
* - We generate one build.ninja and one rules.ninja per project.
* - We try to minimize the number of generated rules: one per target and
* language.
* - We use Ninja special variable $in and $out to produce nice output.
* - We extensively use Ninja variable overloading system to minimize the
* number of generated rules.
