From 8fc2c1dd05e48c3a4230a0dad881186f52694a6e Mon Sep 17 00:00:00 2001
From: =?utf8?q?Jos=C3=A9=20Matox?= <jamatos@lyx.org>
Date: Thu, 27 Jul 2006 18:30:13 +0000
Subject: [PATCH]         * LyX.py 	* lyx_1_1_5.py 	* lyx_1_2.py 	*
 lyx_1_3.py 	* lyx_1_4.py 	* lyx_1_5.py

	* parser_tools.py: remove functions that are not generic, i.e.
assume a specific pattern for the file format, and move them to the
places where they are used.
