From 76fdde3ca84a2cb6ce204e973f2386ac0738957b Mon Sep 17 00:00:00 2001
From: Pascal Rigaux <pixel@mandriva.com>
Date: Tue, 11 May 2004 23:09:34 +0000
Subject: - new function locale_to_main_locale() to replace the typical
 substr($lang, 0, 2) or $lang =~ /(..)/ - new function analyse_locale_name()
 to replace various regexps on locale name - use those 2 functions for cleanup
 - cleanup even more standard_locale()
