################# ./travis.sh #################
# This script takes care of the common steps 
# found in the frappe_docker Travis CI builds. 
#
#   Usage: [-a | -s | -w | -h] [-n <name of service>] [-t <tag> | -g <version number>] [-o]
#
# Argumets:
#
#   -a | --assets (exclusive): Build the nginx + static assets image
#   -s | --socketio (exclusive): Build the frappe-socketio image
#   -w | --worker (exclusive): Build the python environment image
#   -h | --help (exclusive): Print this page
#   
#   -n | --service <name of service>: Name of the service to build: "erpnext" or "frappe"
#     Note: --socketio does not respect this argument
#     Note: This will build an image with the name "$SERVICE-assets" (i.e. "erpnext-worker", "frappe-assets", etc.)
#
#   -t | --tag <tag> (exclusive): The image tag (i.e. erpnext-worker:$TAG )
#   -g | --git-version <version number> (exclusive): The version number of --service (i.e. "11", "12", etc.)
#     Note: This must be a number, not a string!
#
#   -o | --tag-only: Only tag an image and push it.
