# This script parses the README.md and generates a machine-readable
# data structure from it, for publication as an API.
#
# https://springload.github.io/awesome-wagtail/api/v1/readme.json
#
# It is automatically ran as part of Travis builds, also validating the README
# formatting, and the API endpoint is deployed on successful builds on master.
