use the output from gst-xmlinspect.py to mangle tmpl/*.sgml and
insert/overwrite Short Description and Long Description

# FIXME: right now it uses pygst and scans on its own;
# we really should use inspect/*.xml instead since the result of
# gst-xmlinspect.py is commited by the docs maintainer, who can be
# expected to have pygst, but this step should be done for every docs build,
# so no pygst allowed

# read in inspect/*.xml
# for every tmpl/element-(name).xml: mangle with details from element
