# This is an RVM Project .rvmrc file, used to automatically load the ruby | |
# development environment upon cd'ing into the directory | |
# First we specify our desired <ruby>[@<gemset>], the @gemset name is optional, | |

# file. This is very fast and efficient 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. | |
