GCC stand-alone toolkit live CD

[Matteo]

I'd like to build a stand-alone toolkit live CD for developers with the
latest GCC tools (compilers, debuggers, libraries and so on) to can be used
from a CD, a usb key disk or a ram disk contening just an editor and the
compilers tools without intalling anything and how to update all that.
I hope to have been able to explain what I mean.
Thank you very much for the attention.

Best Regards,
Matteo
