Developing themes for LiveCD/DVD

[Michael Rainey]

Hello,

I'm currently working on a project for my local LUG creating a LiveDVD 
to hand out to other organizations and groups.  I would like to design a 
theme to place on the LiveDVD which displays some information.  The 
problem I am having is adding the theme to the LiveDVD when running the 
grub-mkrescue command.  Is there any documentation which covers this 
issue?  So far, everything I've found covers adding themes to existing 
GRUB installs.  How do I design and test a theme without it touching my 
existing GRUB configuration?

Thanks in advance,

Michael
