One war at a time, Alex. If we try to replace the whole Makefile system

You may be right. But CML2 is simpler than what it's replacing by a
large (and readily measurable) factor, so it's a net win to make that
change anyway. *Then* we can go clean up the rest of the build

If that were possible, I have little doubt it would have been done already.
But I tell you what. After phase II, when we fix the rest of the build
system, I promise to seriously re-examine the question of whether CML2
is really needed. If it isn't, we'll throw it away.
I mean that. There are other uses for CML2 -- VA wants me to make it
into a product configurator, among other things -- so the work won't
have been wasted even if we throw away the kernel rulebase.

False is the idea of utility that sacrifices a thousand real advantages for one imaginary or trifling inconvenience; that would take fire from men because it burns, and water because one may drown in it; that has no remedy for evils except destruction. The laws that forbid the carrying of arms are laws of such a nature. They disarm only those who are neither inclined nor determined to commit crimes. -- Cesare Beccaria, as quoted by Thomas Jefferson's Commonplace book
