> There's no license legally possible. Apparently things are a bit more complicated than this, since works created by government employees are in the public domain in the US, but foreign copyrights are still held by the government. Unless the software is released with a FOSS license where applicable, I don't think public domain government code is compatible with other FOSS licenses (which are generally worldwide). Even if it weren't the case that the US government held full copyrights abroad, it's still something of a problem because some jurisdictions do not have a concept of public domain - this is why the concept CC-0 licensing comes into play (it's public domain with a permissive license fallback).
