Extracting ISO Images-How?

[mark at diabro.jp (Mark Sargent)]

Hi All,

I am looking at extracting UBCD ISO and installing modules via Insert to 
use some extra tools when cloning a CentOS install. How is this done via 
cli? I did a google search, but nothing seems clear to me at the moment. 
Could someone point me in the right direction? Cheers.
