lguest: documentation I: Preparation

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.

+Welcome, friend reader, to lguest.
+
+Lguest is an adventure, with you, the reader, as Hero.  I can't think of many
+5000-line projects which offer both such capability and glimpses of future
+potential; it is an exciting time to be delving into the source!
+
+But be warned; this is an arduous journey of several hours or more!  And as we
+know, all true Heroes are driven by a Noble Goal.  Thus I offer a Beer (or
+equivalent) to anyone I meet who has completed this documentation.
+
+So get comfortable and keep your wits about you (both quick and humorous).
+Along your way to the Noble Goal, you will also gain masterly insight into
+lguest, and hypervisors and x86 virtualization in general.
+
+Our Quest is in seven parts: (best read with C highlighting turned on)
+
+I) Preparation
+        - In which our potential hero is flown quickly over the landscape for a
+          taste of its scope.  Suitable for the armchair coders and other such
+          persons of faint constitution.
+
+II) Guest
+        - Where we encounter the first tantalising wisps of code, and come to
+          understand the details of the life of a Guest kernel.
+
+III) Drivers
+        - Whereby the Guest finds its voice and become useful, and our
+          understanding of the Guest is completed.
+
+IV) Launcher
+        - Where we trace back to the creation of the Guest, and thus begin our
+          understanding of the Host.
+
+V) Host
+        - Where we master the Host code, through a long and tortuous journey.
+          Indeed, it is here that our hero is tested in the Bit of Despair.
+
+VI) Switcher
+        - Where our understanding of the intertwined nature of Guests and Hosts
+          is completed.
+
+VII) Mastery
+        - Where our fully fledged hero grapples with the Great Question:
+          "What next?"
+
+make Preparation!
+Rusty Russell.
