lguest: documentation I: Preparation

Browse Source 
The netfilter code had very good documentation: the Netfilter Hacking HOWTO.
Noone ever read it.

So this time I'm trying something different, using a bit of Knuthiness.

/* Simple program to layout "physical" memory for new lguest guest.
* Linked high to avoid likely physical memory. */
/*P:100 This is the Launcher code, a simple program which lays out the
* "physical" memory for the new Guest by mapping the kernel image and the
* virtual devices, then reads repeatedly from /dev/lguest to run the Guest.
*
* The only trick: the Makefile links it at a high address so it will be clear
* of the guest memory region. It means that each Guest cannot have more than
* about 2.5G of memory on a normally configured Host. :*/
