I don't think it would be nearly that large in perl.

Can I read this as "IF AND ONLY IF we have full perl equivelents of
the shell tools required to autoconf can boost use it." ?
If so where do I send the Perl scripts? :-)
I really really dislike Jam as the booststapping is a royal
pain just to replicate what virtually every unix box has already.
Perl tools for cp, m4, sed, awk, sh, which just enough support
for auto* tools really should not be large or invasive.
