From b9913bf54bb7de5407f9216f1cb883a120716de4 Mon Sep 17 00:00:00 2001 From: Ed Bartosh Date: Wed, 1 Aug 2012 14:55:15 +0300 Subject: [PATCH] Get rid of local copy of cmdln.py In the current code thereis a copy of cmdln.py module, which is also present in osc. gbs depends on osc, so it's better to just use cmldn from there to avoid unneeded code duplication.
