Hi Eric,

now i know why we haven't heard of you for some time: you have
been very busy... ;-)

So we are back a C sources. Let me ask you one thing: why not simply
use ISO-C and be done with it? There are excelllent tools like yacc
and lex for building parsers, why don't you use them to generate C
code instead on an obscure script language. I know you really like
Python, but face it: 90% of the folks on this list probaly don't.

Let me put it that way: the only dependancies the kernel sources should
have are GNU-make, GNU-binutils, GNU-C and the standard Unix tools (sed,
awk, sh, ...). Both perl and python do not belong into any of these
categories and should not be used. The perl dependency is not critical
at the moment, because you can build a kernel without using these tools,
but it should be removed ASAP. Remember that we had ksymoops rewritten
to remove the C++ dependancy?

I really don't like the added complexity. IMHO we should ditch our current
config scheme in favour of the BSD tools if at all: They are written in
C, they are simple to use and they have a proven track record. What more
is there to ask?
