#
#   DESCRIPTION:
#             From nginx-add-meteor-vhost:
#                This script will add a virtual host configuration file to
#                 the Nginx sites-available/ directory and then creates a
#                 symbolic link to that file in sites-enabled/.
#                The file is named <host>.conf and will be configured to run
#                 under the supplied user name using the app bundle in their
#                 ~/www/bundle directory.  It will be handled by Passenger
#                 and served on via regular HTTP on port 80.
#               A user will be created and the home directory will have a
#                 symblolic link named www (~/www/) that leads to their web
#                 application directory, /var/www/<user>.  Note that on my
#                 Amazon Meteor Server 1 AMI, /var/www/ is a symbolic link
#                 to /opt/www/.
#               The app will be given a Mongo database @ localhost:27017/<user>.
#             Then:
#               The script will bundle local application source, send the
#                 tarball to the new user's home directory and finally deploy
#                 by calling meteor-unbundle-and-deploy.sh.
#       OPTIONS:
#                -b | --bundle
#                   Default = '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.
#                -d | --dir
#                   Default = ./
#                   Location of your app's Meteor root (ie; has contains .meteor)
#                   If omitted, assumes that your pwd is that the app root
#                -f | --force
#                   Passing the force flag will suppress the prompt to restart
#                     nginx and just do it.
#                -h | --host
#                   * Required
#                   The fully qualified domain name of the virtual host.
#                -i | --key
#                   The SSH public key file for the given user and server.
#                -n | --new
#                   The name of the remote system account the vhost will be
#                     attributed to.
#                   If their home directory already exists, vhost creation will
#                     be skipped
#                -r | --remote
#                   The fully qualified domain name of the remote server.
#                -s | --settings
#                   Location of your app's JSON settings file, which will then
#                     be inserted into the Nginx configuration file.
#                -t | --temp
#                   Defaults = '~/www/tmp'
#                   Name of temp directory to create with meteor bundle -directory
#                -u | --user
#                   The remote user name to use when logging in with SSH.
#                -v | --verbose
#                   If passed, will show all commands executed.
#  REQUIREMENTS: Nginx, Passenger, Node 0.10.43, Meteor locally installed, ~/www/,
#                 @iDoMeteor amazon-scripts installed in user paths on the remote
#                 server as well as in ~/bin or ~/amazon/scripts on the local.
#          BUGS: ---
#         NOTES: Script will look for 'meteor-unbundle-and-deploy.sh' in the
#                 following locations in order from top to bottom:
#                   * ~/amazon/scripts/
#                   * ~/bin/
#                   * <app-dir>/private/scripts/
