# This script use apigen to generate the documentation for the
# repository configured above. When run locally, the documentation
# will be placed in the 'docs' folder.
# However this script can also be run from travis. This requires
# the setup of a secret token as described at http://bit.ly/1MNbPn0
#
# Additional configuration can be done within an apigen.neon file
#
# ---- no modifications below ---------------------------------------
