/home/brian/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/bin/rustdoc [options] <input>

Options:
    -h --help           show this help message
    -V --version        print rustdoc's version
    -v --verbose        use verbose output
    -r --input-format [rust]

No other rust tools do this. Just hard-code 'rustdoc' here.

I'll take a crack at it. Quickly looking at the code this is probably where it messes up right?
