From 3dc52164fb560ccbe5c203a4587f6286c8fc0389 Mon Sep 17 00:00:00 2001 From: Randy Witt Date: Mon, 23 Feb 2015 17:00:37 +0000 Subject: copy_buildsystem.py: Add a way to copy buildsystem to a directory. This file provides a way to take bitbake and the layers in the current build and copy them to a target specified.
