## Incremental builds

You can configure rustbuild to use incremental compilation. Because
incremental is new and evolving rapidly, if you want to use it, it is
recommended that you replace the snapshot with a locally installed
nightly build of rustc. You will want to keep this up to date.

To follow this course of action, first thing you will want to do is to
install a nightly, presumably using `rustup`. You will then want to
configure your directory to use this build, like so:

```sh
# configure to use local rust instead of downloading a beta.
# `--local-rust-root` is optional here. If elided, we will
# use whatever rustc we find on your PATH.
$ ./configure --local-rust-root=~/.cargo/ --enable-local-rebuild
```

After that, you can use the `--incremental` flag to actually do
incremental builds:

the stage1 compiler is changing, and we don't try to cache and reuse
incremental artifacts across different versions of the compiler. For
this reason, `--incremental` defaults to `--stage 1` (though you can
manually select a higher stage, if you prefer).

You can always drop the `--incremental` to build as normal (but you
