rvmrc - add your gemset name

.rvmrc

#!/usr/bin/env bash

# development environment upon cd'ing into the directory

# First we specify our desired <ruby>[@<gemset>], the @gemset name is optional.

# First we attempt to load the desired environment directly from the environment
# file, this is very fast and efficicent compared to running through the entire
# CLI and selector. If you want feedback on which environment was used then
# insert the word 'use' after --create as this triggers verbose mode.
