Correctness comes first, but I think the article was reasonably fair. The
author is trying to find a build system to solve a real-world problem. The
requirements that it should be fast, simple to customise for other
platforms and tools and perform as well on incremental builds as on full
rebuilds seem a reasonable place to start. If the synthetic benchmark he
uses seems unfair, please produce some constructive criticism as to how it
can be made more realistic.

Returning to the title of the thread, the only things I've used BBv1 and
BBv2 for are building Boost itself, and some toy projects (the exercises
from the TMP book). Based on that (limited) experience, I would not
consider [b]jam or BoostBuild for any serious work. Producing a language
with more baroque and undebuggable syntax and semantics than 'make' takes
some doing.

I think that the effort expended on BBv1/BBv2 would have been far better
spent on fixing the performance issues in scons.
