I see Changming's email about nesting this in the folder as well.  No
issue with that as long as the maintainers support it (similar to
freescale-imx)

On the next branch there is a patch applied that allows custom board
rcws to meet that need.

Agree, the package was originally setup to stage all the pieces the
user needs to use the tool outside of the build from a deployed SDK
for creating images (mainly a board bringup/hardware developer use
case).  REcently a patch was applied to Next that allows customized
boards and with Changming's patch you can stage pre-defined board rcw
binaries for use.
