One thought about the abi name: it pretty much guarantees that we won't be able to publish this crate to crates.io without doing another rename. Are we happy with that?

(Please wait on @tiziano88's review, as he understands crate resolution etc. rather better than I do.)

[tiziano88]

will take a look shortly, but yes, crates live in a global namespace, so abi is not specific enough (as a matter of fact, even oak_abi was already taken, so we probably need something even more specific)

[daviddrysdale]

Aside: oak_abi looks free at the moment, but oak_runtime isn't.

[rbehjati]

I changed the name to oak_abi for now.

[tiziano88]

FYI I think having "fix #xxx" in the commit message will cause the issue to be marked as fixed. If that's not the intention, use "ref #xxx" or just "#xxx".

[tiziano88]

Why not keep this and just redirect it to the new location?

[rbehjati]

Oh! This works! Thanks.
