# High-performance, native SSH implementation for Jenkins SSH slaves. Jenkins'
# standard turn-key SSH slave implementation uses an embedded, "pure Java"
# implementation of SSH (https://github.com/jenkinsci/trilead-ssh2).
# That standard implementation combines all of the convenience of a pure Java
# implementation with all of the "performance" of a pure Java implementation :P

# If your distributed build process generates large build artifacts like ISOs,
# VM images, Vagrant boxes, etc, then you will see a substantial benefit from

Requirements

• RVM (or rbenv, but this will use RVM)
• You're using RVM or rbenv to manage your rubies, right? If not, you should be.
• Virtualbox
• some cookbooks you wrote and want to test

Set it up

We don't want to mess up our carefully crafted Chef 10.x environment, right? We'll use rvm gemsets to make a disposable set of gems. If something goes wrong, just close the terminal you're in, or run rvm gemset use default. You'll drop back to the default gemset.
