# This script is a web based form for testing the RDF agent
# on a specified user URL. When the script is called without
# parameters, a FORM is generated.
#
# Parameters understood by this script:
# url - the remote url of the RDF doc that the agent will fetch
# NOTES:
# 1. This script assumes that a BioMOBY registry is properly
# installed
# 2. JAVA_HOME is set in the environment or 'java' called
# at a command prompt actually calls a java runtime.
# 3. This script attempts to ensure that the arguement passed
# in is a 'real' url by first calling head on the URL.
# I am not sure if this will cause problems later on.

one or more moby services. The agent will then attempt to
resolve and parse that url.
Once the agent is complete, you should see what services were
considered valid and what errors occurred below.
