Instead of outputting to this location you should should have the "mus" target
list the resources it needs in resources. This way they'll be copied correctly.

Didn't realize that was a thing. Done. The only thing that seems concerning is
now the //ash/mus:lib target doesn't actually include in the resources it needs,
the //ash/mus target is what has them, so that could cause problems down the
line if someone else includes //ash/mus:lib?

[sky, 2016/04/11 15:00:30]

I think that's the common pattern, even for non-mus apps. The resources are
listed in the executable target. If there is a better way where resources can be
listed in any targets, it would be good to change it.
