[syslinux] .spl files

[lyric hartley]

I am not certain that this is the right place to post this, but maybe
some kind soul can point me in the right direction if not. And I
apologize if this is the wrong spot...The reason I posted here is that
I recall running across a syslinux changlog that said "..added support
for reading .spl..." files. I want to customize the suse boot up
splash screens (for a CD install). I have been attacking it from the
gfxboot and bootsplash side of things...but I believe that the
[resolution].spl files they supply are one of my final links...I have
searched and searched but can not seem to find any docs about
using/creating these archives(?)...so, any advice would be greatly
appreciated!

thanks
Lee
