Rubyx is a ruby based linux distro. It is also the name of the script which
creates Rubyx the distro and handles the package management

In light of the recent rubyx/lunar threads, I thought it sensible to
make the
rubyx source available for scrutiny by the ruby community. You can get it
using Bitkeeper like this:

bk clone bk://ftp.rubyx.org/rubyx
cd rubyx
bk co

You'll see three files;

rubyx	The man script
init		The ruby based init script
strfile.rb	Some code shared by rubyx and init

as root, ./rubyx --help should give you

Important! The build machine must be capable of running the generated code,
For example;
~ You need a pentium4 build machine to use --cpu pentium4
~ You need an athlon64/opteron build machine to use --cpu opteron
~ (but its ok to build 64 bit distro from operton running 32bit os as
long as
kernel is 64bit)

How it all works will require further discussion, but if you want to get
involved, it would be a good idea to ask rubyx to download the sources. To
get everything, you'll need 4Gb and broadband ;) For just the basics,
it's a
fraction of that but I don't have the figure to hand. Do this as root...

mkdir /my/rubyx/dir  (or something like)
/rubyx --root /my/rubyx/dir --download base net disk (for the basics)
/rubyx --root /my/rubyx/dir --download all (for everything)

If you don't have broadband, you might want to use --dj 1 to reduce the
number
of parallel downloads.

I wrote this in part to learn ruby, so any comments/suggestions on the
code or
style are welcomed. Although I am writing this in Kmail on my laptop
running
Rubyx, rubyx is still very much work in progress, so don't expect too much.
Lots more to discuss, but this will do for starters :)
