# This is a shart script to get demo content to populate an inial set of 'science gists'
# We started by trying to call the elife api directly, but it sucked balls
# then we tried to use content negotiation, but that is also flakey

# finally we will had insert the path the the XML
# pass the full xml to nokogiri
# then extract the xml node '<abstract abstract-type="executive-summary"'
