From ad27739cd87a75b172fd415fc20db08983ea4e13 Mon Sep 17 00:00:00 2001 From: Vratko Polak Date: Tue, 10 Jul 2018 14:07:02 +0200 Subject: CSIT-1186: Consume MLRsearch in agreed upon way + Rename search to MLRsearch in resources/libraries/python/. + Make PyPI/MLRsearch/MLRsearch a symlink to the renamed directory. + TrafficGenerator.py to import from the renamed directory/module. - No change to MLRsearch code. - Version stays at 0.1.1 to point to the latest released code.
