From c09a6d6c0c9d0e9056816f518171864158c72076 Mon Sep 17 00:00:00 2001 From: Bram Moolenaar Date: Mon, 10 Jun 2013 21:27:29 +0200 Subject: updated for version 7.3.1163 Problem: Not easy to load Python modules. Solution: Search "python2", "python3" and "pythonx" directories in 'runtimepath' for Python modules.
