The BitBucket repository is down for the moment. Kigen childishly issued a DMCA takedown request against it rather than waiting for the miniscule amount of his code that was left in the project to be documented to his exact specification. BitBucket removed the project immediately without any question or fact-finding.
We'll look to get it up somewhere else in the near-ish future, without any of Kigen's code remaining so that we are not bound by his antics.
Edit: It's now available again in the stickied SMAC Download thread.
