From ac053163c7823e482ca1af2962342e64a54bfb52 Mon Sep 17 00:00:00 2001 From: Christopher Larson Date: Wed, 16 Sep 2015 10:03:32 -0700 Subject: recipetool: add 'newappend' sub-command This sub-command creates a bbappend for the specified target and prints the path to the bbappend. The -w argument, as with some of the other recipetool commands, will make a version-independent bbappend.
