Hi Matthew,

Thanks! I had packaged rustfmt-nightly but this is much better.

Nice!

Perhaps we should make anything that can be installed as a rustup
component an output (provided the source is in the rust tree). I think
rls can be added immediately in the same fashion.

Do you want to add a copyright line?

Otherwise, this looks good to me.

Best regards,

John
