# -----------------
# Control variables (Travis Settings)
# -----------------
#
# PUBLISH_IMAGES        Should be 'yes' to enable publishing to Docker Hub.
#
#                       NOTE: Pull requests from forked repositories will not
#                       result in encrypted variables being set.
#                       So, regardless of the state of PUBLISH_IMAGES,
#                       images will only be published if DOCKER_PASSWORD is defined.
#
# If you set PUBLISH_IMAGES you must also set the following: -
#
# DOCKER_USERNAME       If PUBLISH_IMAGES is 'yes'
# DOCKER_PASSWORD       If PUBLISH_IMAGES is 'yes'
#
# You control the Backend container's source and destination image names with...
#
# BE_NAMESPACE          To over-ride the default namespace of the image
#                       (which is 'xchem')
#
# To trigger the dependent, downstream builds (like the Stack and Loader)...
#
# TRIGGER_DOWNSTREAM    Should be set to 'yes'
#                       Enabling TRIGGER_DOWNSTREAM is only effective
#                       if PUBLISH_IMAGES is also set.
#
# The following required if TRIGGER_DOWNSTREAM...
#
# TRAVIS_ACCESS_TOKEN   A Travis token
#
# STACK_NAMESPACE       To define the namespace of the Stack repository (default is 'xchem')
# STACK_BRANCH          The branch to trigger (default is 'master')
# LOADER_NAMESPACE      To define the namespace of the Loader repository (default is 'xchem')
# LOADER_BRANCH         The branch to trigger (default is 'master')
