There's not a lot of code in Yamoxic currently, but I've decided to post what I've done so far. But don't get your hopes up. It's in a very early stage of development, and doesn't even have support for actually connecting anywhere yet.
Note: The snapshots also include the Netclasses library. This is because I want to be able to work on Netclasses in the same Xcode project as Yamoxic. (This is a good thing for several reasons.)
Also note: Netclasses/IRCObject.[hm] aren't actually used in Yamoxic, though they're built and linked for completeness. (They are an IRC implementation within netclasses itself, which I don't need since Yamoxic uses Icecap.)
Also also note: These snapshots aren't uploaded on a regular basis. The most up-to-date development version is available only via SVN.
