# This script will attempt to enumerate RMI interfaces and their exposed
# methods using JRuby.
#
# The script takes one argument, which is the URL for a remote RMI registry.
# Example:
#
# rmiquery.rb //127.0.0.1:1099
#
# Method names and prototypes are only available if RMI application stubs are
# included. You can include them by dropping their JAR or class files into
# the same directory that you run this script from and they will be
# automatically loaded.
#
# For info on RMI:
