should rustpkg install examples/foo install the binary into bin/foo?

[erickt]

If we have a simple repo with src/examples/foo/main.rs in it, doing rustpkg install examples/foo will put the binary into bin/foo, but this risks binaries stomping on each other. There are three reasons why I could see you might want to do this: examples, tests, and internal binaries that are needed to compile the project.

One thing that could help is if rustpkg grew a run command. This would allow you to portably run an example/test/internal tool. This would eliminate a couple of the reasons why you might want to install binaries.
