Breakout

[qrush]

Broke out ports and commands to modules.

I don't know why I can't move the regexp extern lines to start.rs. I tried to download the nightly to see if it was resolved and rust-lang/rust#21456 happened. I think this is an OK start though, what say you @carols10cents ?

extern crate needs to go in the crate root, that way, Rust can know everything that you need to link to by just examining one file. It's possible that nowadays, Cargo might be able to figure it out anyway, but this behavior is pre-cargo. I think we have an RFC to relax this...

[qrush]

Which extern crate exactly? Because if you put it in the root (main.rs) and take it out of ports.rs for example, it does not compile.

[steveklabnik]

All extern crates should be in the root, and Rust should warn you otherwise. Buutttttttt if you're not seeing that, time to look through the commit logs...

[qrush]

Nope, it complains massively and won't compile at all if you attempt to move things out. Maybe I set up the packages/mod/folders wrong. I'd be happy to screenshare later tonight to show if that helps.

[steveklabnik]

let me actually grab the source and see what's up

ahhh so rust-lang/rust#18219 and rust-lang/rust#20179 should certainly make the behavior i'm talking about nicer, but it's strange because it seems to already be behaving that way...
