#
#         USAGE: meteor-unbundle-and-deploy.sh -b bundle-name [-v]
#                meteor-unbundle-and-deploy.sh --bundle bundle-name [--verbose]
#
#   DESCRIPTION: This script untars a tarball bundled by Meteor to a temporary
#                 location, runs node install & prune, and then replaces an
#                 existing bundle with the new one.
#                Once this is complete, the script will restart the app's
#                 Passenger process and remove's the temporary directory.
#                It is left to the user to remove the replaced bundle, which
#                 will be renamed bundle.old.
#                This script will generally be run automatically by the remote
#                 developer's meteor-bundle-and-send script.
#       OPTIONS:
#                -b | --bundle
#                   The name of your bundle, <bundle-name>.tar.gz.
#                   I recommend making them descriptive and versioned, so
#                    that you can easily switch versions in emergencies.
#                -v | --verbose
#                   If passed, will show all commands executed.
#  REQUIREMENTS: Node 0.10.43, Passenger
