And then we pile language on top of language. One thing we wanted to
avoid with Boost.Build was the autoconf syndrome where in order to
understand the system you need to learn four different programming

And furthermore that requires people to have Perl installed, which at
the time was out-of-the-question for some Boost developers and IMO is
still a ridiculous thing to demand of a Windows programmer who wants to
use Boost.

It seems to me that waving off the ways in which your hypothetical
system doesn't satisfy the requirements without having done the hard
work of building a system that does satisfy them doesn't help your case.
By the way, what case are you trying to make, anyway? Are you just
trying to tell me that my answers to the OP's questions are wrong, or is
it more than that?
