# This assumes three things:
#
# 1) That you have an SSH server running on your local machine,
# 2) That the USER environment variable is set to your user name, and
# 3) That you have public and private keys conigured so that you can log into
#    your machine via SSH without being prompted for a password.
#
# If #2 or #3 are not true, you can add your user-name and password as the
# second and third parameters (respectively) to Net::SSH.start.
