 final reltool step, the variable needs to be set in pkg.vars.config
 (or defaulted in <osname>.template) AND be present in the vars.config,
 so it can be applied to the reltool templates.

+*** Example App
+
+The easiest app that uses =node_package= is [[https://github.com/basho/stanchion][stanchion]] a small application that Basho uses along side Riak CS.

+In particular, see:

+ -  [[https://github.com/basho/stanchion/blob/develop/Makefile#L73][makefile]]
+ -  [[https://github.com/basho/stanchion/blob/develop/rel/reltool.config#L46][reltool.config]]

+It also has custom settings in its [[https://github.com/basho/stanchion/blob/develop/rel/vars.config#L31][vars.config]] for adjusting settings in the =bin/stanchion= that comes from node_package's =runner= script.
