+# NOTE: Armband patching consists of:
+# - clone upstream repositories to git submodules;
+# - checkout submodule commits where set in Fuel@OPNFV's config.mk
+# (e.g. FUEL_ASTUTE_COMMIT=...);
+# - tag each submodule (before patching) with "armband-workbench-root";
+# - apply Armband patches for each submodule;
+# - tag each submodule (after patching) with "armband-workbench";
+# - pass updated repository info to Fuel@OPNFV build system
+# (e.g. FUEL_ASTUTE_COMMIT=HEAD) via armband.mk;
+
+# NOTE: Long-term goals (Armband repo should merge with Fuel@OPNFV):
+# - all build related changes should affect Fuel@OPNFV, NOT Armband;
+# - Armband make/build system should only handle patching,
+# including eventual build related patching of Fuel@OPNFV,
+# and then invoke Fuel@OPNFV's build system;
+# - Fuel@OPNFV is made aware of an Armband type build by passing
+# the "ARMBAND_BASE" env var;
+
+# Fist, inherit Fuel submodule commit references from Fuel@OPNFV
+# using "config.mk" as a make target that links to Fuel's config.mk.
+# Some values will be overriden at Fuel ISO build time by armband.mk.
