The content of the file is documented at:

http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/

... although extlinux.conf is a single file containing all the entries, 
rather than a separate *.conf per OS. I'm not sure where that aspect of 
the file is documented. Dennis, do you know where?

FWIW, the concept of a single file rather than many *.conf has been 
embodied in U-Boot's pxe and sysboot commands for some time, and isn't 
anything to do with this patch set.
