Otherwise, clone rbenv-gemset to the `$HOME/.rbenv/plugins` directory:

    $ mkdir -p ~/.rbenv/plugins
    $ cd ~/.rbenv/plugins
    $ git clone git://github.com/jamis/rbenv-gemset.git

## Usage

In your application directory, create a file named `.rbenv-gemsets` and put the
names of the gemsets you want to use in it, separated by whitespace. The first
gemset in the list will be the primary gemset, where new gems will be
installed.

    $ echo my-gemset > .rbenv-gemsets
