Node Version Manager (v0.39.2)

Note: <version> refers to any version-like string nvm understands. This includes:
  - full or partial version numbers, starting with an optional "v" (0.10, v0.1.2, v1)
  - default (built-in) aliases: node, stable, unstable, iojs, system
  - custom aliases you define with `nvm alias foo`

 Any options that produce colorized output should respect the `--no-colors` option.

Usage:
  nvm --help                                  Show this message
    --no-colors                               Suppress colored output
  nvm --version                               Print out the installed version of nvm
  nvm install [<version>]                     Download and install a <version>. Uses .nvmrc if available and version is omitted.
   The following optional arguments, if provided, must appear directly after `nvm install`:
    -s                                        Skip binary download, install from source only.
    -b                                        Skip source download, install from binary only.
    --reinstall-packages-from=<version>       When installing, reinstall packages installed in <node|iojs|node version number>
<__SNIP blah blah blah lots of output___>
