# CoNLL-RDF+POWLA EXAMPLE: 
# - read CoNLL file with several phrase structure parses
# - represent parses as powla:Nodes
# - write the first of the parses to stdout

# Treatment of empty nodes (that do not contain a nif:Word) left as an excercise.
# See xml-example.sh for their treatment in XML parsing
