# Add a Parameter to the Cluster
parameter = Parameter("-", "name", lambda name: name)
parameter.set_required(True)\
.set_description("Your name.")
parameters.add(parameter)
# Create a new Parser using the Cluster
parser = Parser(sys.argv, parameters)
# Parse the parameters using the Parser.
results = parser.parse()
# Verify that the parameters were valid after parsing.
if not parser.is_valid():
# Since it was not valid, output usage.
