From 1a2576036b3377ec83a08b7238f59dc474053543 Mon Sep 17 00:00:00 2001
From: Dries Buytaert <dries@buytaert.net>
Date: Thu, 12 Jun 2003 17:24:06 +0000
Subject: - Bugfix: charset fixes/clean-up.  Patch #52 by Al.

- Improvement: renamed some theme functions of the forum module for sake of consistency/readability.  Patch #2 by Kristjan.

- Improvement: usability improvements to the Xtemplate theme.  Patch #3 by Kristjan.

- Improvement: CSS'ified the book module pages.  Patch #3 by Al.  (I simplified the "l
ocation" part.  Al's approach gave you a bit more power but I'm not sure anyone wants
to change that.  Besides, this will change as soon we integrate the menu system so I kept it easy for now.)
