And also some small addition: It might happen that the enterprise wide
common repo contains boost, but the version, which does not feature the
desired lib. What do you do then? Switching the boost version must be tested
within all dependent projects. This is not that trivial. I understand, that
in ideal world a boost lib distro is just updated as soon as it is out, but
it might be not the case for various reasons.
