[J.Bakshi]

Dear list,

In my debian lenny, the grub2 has very simple look. I know it can be tweak to 
get ubuntu style graphical grub2 interface. After searchine google I have 
found the Grub2 summer code project 2008 and I have downloaded the theme 
folder. But I can't understand how to include the theme file in grub.cfg.
Please let me know how to use those theme with grub.cfg.

with regards,
J
