Where is documentation for rustc and cargo?


Didn’t found answer in previously asked questions.
I got advice to look at cargo’s repository, but it only contains documentation for cargo rustc subcommand, not to rustc itself.

Then I found file at ~/.multirust/toolchains/stable-x86_64-unknown-linux-gnu/share/man/man1/rustc.1, however viewing it by executing nroff -mdoc file | less renders it distorted. So I think, that file is somewhat malformatted.

Where to find the most recent man pages for utilities?
