# Before `make install' is performed this script should be runnable with

# A script to test the Wu & Palmer (wup.pm) measure.  This script runs the
# following tests:
#
# 1) tests whether the modules are constructed correctly
# 2) tests whether an error is given when no WordNet::QueryData object
#    is supplied
# 3) simply getRelatedness queries are performed on valid words, invalid
#    words, and words from different parts of speech
