First off, great distro. It needs more documentation, and some of the 
builds don't work, but overall, it is *very* cool.

I just have a couple of questions. First, what optimizations are used 
in compiling the latest (RC4_pre2 I think) distribution? I read the 
article about the development of Gentoo and at the end you said that 
you would use -mpentium -O2 optimizations. However, the make.defaults 
uses the -m486 optimizations. I would just like some clarification on 
which one was used to build the distro. Also, I was wondering if one 
could automatically recompile the distro using -mpentiumpro 
optimizations, something along the lines of BSD's make World. Thanks 
for your time,
	Rayiner Hashem.

Yeah, you can change the CFLAGS line in make.defaults. Then,
everything you build from then on will use that value for
optimizations.

The build listed in current-packages.new should all work. If you see a
newer version that is not listed in current-packages.new you can
consider it being in development/testing.



 but overall, it is *very* cool.

Previous we used -mpentium  and i686 as ARCH. But that caused trouble 
on K6 prozessors so we decided to use i484 and -m486 for rc4_pre2.
rc4 final will be available for different targets.
