Many `rustup` commands deal with *toolchains*, a single installation
of the Rust compiler. `rustup` supports multiple types of
toolchains. The most basic track the official release channels:
'stable', 'beta' and 'nightly'; but `rustup` can also install
toolchains from the official archives, for alternate host platforms,
and from local builds.

Standard release channel toolchain names have the following form:
Standard release channel toolchain names have the following form:

'channel' is either a named release channel or an explicit version
number, such as '1.8.0'. Channel names can be optionally appended with
an archive date, as in 'nightly-2014-12-18', in which case the
toolchain is downloaded from the archive for that date.

Finally, the host may be specified as a target triple. This is most
useful for installing a 32-bit compiler on a 64-bit platform, or for
installing the [MSVC-based toolchain] on Windows. For example:

Directories can be assigned their own Rust toolchain with

pub static COMPLETIONS_HELP: &'static str =

One can generate a completion script for `rustup` that is compatible with
a given shell. The script is output on `stdout` allowing one to re-direct
the output to the file of their choosing. Where you place the file will
depend on which shell, and which operating system you are using. Your
particular configuration may also determine where these scripts need
to be placed.
