From 8ca47e00690914a9e5e6c734baa37c829a2f2fa1 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 19 Jul 2007 01:49:29 -0700 Subject: lguest: the documentation, example launcher A brief document describing how to use lguest. Because lguest doesn't have an ABI we also include an example launcher in the Documentation directory.
