From 4ec75bbee658e4c68b82281f0ee833fcfa15e018 Mon Sep 17 00:00:00 2001
From: Stefano Ceccherini <stefano.ceccherini@gmail.com>
Date: Wed, 4 Jul 2007 20:11:17 +0000
Subject: [PATCH] Big refactoring. Got rid of some global variables by putting
 code in global functions (at least for now), removed useless globals,
 restyled the code. Not yet done.
