+and test configurations.  With PICT, you can generate tests that are more
+effective than manually generated tests and in a fraction of the time required
+by hands-on test case design.  PICT runs as a command line tool.  It takes a
+model file detailing the parameters of the interface as an input and generates
+a compact set of parameter value choices that represent the test cases you
+should use to get comprehensive combinatorial coverage of your parameters.")
