rustup 0.5.0 is out. To get it run rustup self update.
This release features a more convenient syntax for executing tools from an arbitrary toolchain. Instead of e.g. rustup run nightly rustc main.rs, you can now run simply rustc +nightly main.rs. That is, execute the toolchain command directly, and if the first argument begins with + it identifies a toolchain name and uses it. Neat idea from @DanielKeep. Let me know what you think of it.
It also adds the rustup man command, which simply displays a man page for the active toolchain, contributed by @theindigamer; and continued work by @inejge on creating an HTTP backend using the rustls Rust TLS library.
Finally, this contains mitigations against misconfiguring the rustup install by running it under sudo. If it detects that it is about to write root-owned files to a non-root home dir it will complain. This type of systems-integration code can sometimes cause surprises, so I’m interested in wider testing. If you are running a less-used Unix you might try to run the installer again (no need to uninstall first) and see if it does anything unexpected.
Thanks to everybody who contributed, and thanks to everybody for testing, reporting issues and running rustup!
