If neither `--bin` nor `--example` are given, then if the package only has one
bin target it will be run. Otherwise `--bin` specifies the bin target to run,
and `--example` specifies the example target to run. At most one of `--bin` or
`--example` can be provided.

All the arguments following the two dashes (`--`) are passed to the binary to
run. If you're passing arguments to both Cargo and the binary, the ones after
`--` go to the binary, the ones before go to Cargo.
