From 1e45a4f72b16c7ab64f46907d2d2ee9cd749dc23 Mon Sep 17 00:00:00 2001 From: Ed Bartosh Date: Sun, 26 Mar 2017 20:39:22 +0300 Subject: wic: remove unused code from runner module Removed unused APIs 'outs' and 'quiet'. Removed 'catch' parameter from runner.runtool API as wic uses only one value of it. Removed the code that handles unused values of 'catch' parameter.
