in this case it might be simpler to check if these commands are available
and not bother checking which OS you actually have. Another simple alternative
is to mandate an environment variable and simply fuss at the users if it is
not set. I doubt there is something like a general bulet prof OS-detection 
that would stay upwards compatible.
