Hallo.

> icecc seems to do the coloring, too...

This one? http://en.opensuse.org/Icecream

Now i'm being pointed to C++ one. Alright!

== Check this out then. ==

Linus says, make it working somehow and release, so...
I'd like to have it in menuconfig window running gcc on every */M
(i want alot more, without ncurses, perl, C++ using kernel, sh, sed)

extract$ sed '1,/^__/d' >/tmp/lide.sh
use (in OBJDIR)$ clear ; sh /tmp/lide.sh kdefc

kdefc is a user friendly thing for `make defconfig`
ksecmis is one for funny `make CONFIG_DEBUG_SECTION_MISMATCH=y`
any ordinary command will work, no command -- interactive mode.

Coloring and painting is for children, big daddies usually don't get it,
as well as most basic userspace possible(: /bin/sh ).

(any tty braindamage is a cool tty design from 70s, not sh + sed)
