...
Create a custom toolchain by symlinking to a directory

USAGE:
    rustup[EXE] toolchain link <toolchain> <path>

ARGS:
    <toolchain>    Custom toolchain name
    <path>         Path to the directory

OPTIONS:
    -h, --help    Print help information

DISCUSSION:
    'toolchain' is the custom name to be assigned to the new toolchain.
    Any name is permitted as long as it does not fully match an initial
    substring of a standard release channel. For example, you can use
    the names 'latest' or '2017-04-01' but you cannot use 'stable' or
    'beta-i686' or 'nightly-x86_64-unknown-linux-gnu'.

    'path' specifies the directory where the binaries and libraries for
    the custom toolchain can be found. For example, when used for
    development of Rust itself, toolchains can be linked directly out of
    the build directory. After building, you can test out different
    compiler versions as follows:

        $ rustup toolchain link latest-stage1 build/x86_64-unknown-linux-gnu/stage1
        $ rustup override set latest-stage1

    If you now compile a crate in the current directory, the custom
    toolchain 'latest-stage1' will be used.
