# Doxygen HTML help is not suitable for packaging due to a minified JavaScript
# bundle inserted by Doxygen itself. See discussion at
# https://bugzilla.redhat.com/show_bug.cgi?id=2006555.
#
# We can enable the Doxygen PDF documentation as a substitute.
#
# We still generate the HTML documentation, but strip out all the JavaScript
# that causes policy issues. This degrades it in the browser, but is sufficient
# to keep the Devhelp documentation working.
