cargo sweep -t 30

To clean all build files not made by the currently installed (by rustup) nightly compiler:

```
cargo sweep --toolchains="nightly"
```

This can be useful if you checked that your library works on stable, but mostly develop on nightly.


To clean all build files not made by any of the currently installed (by rustup) compilers:

```
cargo sweep -i
```

This can be useful if you just updated your compilers with a `rustup update`.


To preview the results of a sweep run, which is recommended as a first step, add the `-d` flag, for instance:

To clean everything but the latest build you will need to run it in several steps.

**DEPRICATED** This behavior can be too agressive, since cargo can skip reading files when building a near-identical build, see #2 and #11. Also, this will be replaced once `build-plan` is stabilized in cargo.
