From 63750d8c1135d28023f5bd4f0286ea727e86954b Mon Sep 17 00:00:00 2001 From: Scott Rifenbark Date: Wed, 14 Jan 2015 16:27:20 -0800 Subject: dev-manual: Updates to using IMAGE_FEATURES and EXTRA_IMAGE_FEATURES The section "Customizing Images Using Custom IMAGE_FEATURES and EXTRA_IMAGE_FEATURES" needed a bit more clarification on the image features. The text pretty much passed off image features as all mapping into package groups, which is not true. Some, like "debug-tweaks for example, are more like general configurations. I updated the section accordingly. Reported-by: Robert P. J.
