# Targets for daily automated doc build
# By default, Sphinx only rebuilds pages where the page content has changed.
# This means it doesn't always pick up changes to preferred link targets, etc
# To ensure such changes are picked up, we build the published docs with
# `-E` (to ignore the cached environment) and `-a` (to ignore already existing
# output files)
