I wanted an offline copy of the standard library documentation, so I emerged with USE=doc. It looks mostly OK, but not completely: if I look at the “std::os::unix” module, it claims to be a nightly-only API (std_internals) and has no documentation at all. Looking at the same module in the online documentation hosted at rust-lang.org claims that module has been stable since 1.0.0 and has and overview section plus lots of members documented.
