File contents:

#!/usr/bin/env bash

# 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,
# Only full ruby name is supported here, for short names use:
#     echo "rvm use 1.9.3" > .rvmrc
environment_id="ruby-1.9.3-p194@testing_rvm"

# Uncomment the following lines if you want to verify rvm version per project
# rvmrc_rvm_version="1.15.1 (master)" # 1.10.1 seams as a safe start
# eval "$(echo ${rvm_version}.${rvmrc_rvm_version} | awk -F. '{print "[[ "$1*65536+$2*256+$3" -ge "$4*65536+$5*256+$6" ]]"}' )" || {
#   echo "This .rvmrc file requires at least RVM ${rvmrc_rvm_version}, aborting loading."
#   return 1
# }

# First we attempt to load the desired environment directly from the environment
# 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.
