From 1efe10cf62ebf9f0749dd3329ea52f4c9ac2e96b Mon Sep 17 00:00:00 2001

Subject: Add the 'each' and 'release' make targets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 'each' target is used to dump all the different combinations into my
Everdrive so to test on real hardware.

The 'release' target is used so the "DEV" version of the ROM does not
make it into the releases page from Github.
