+features useful for designing tests or question sets: it allows for explicit
+markup of questions and answers; the class will, at the user's request,
+automatically generate answer keys; multiple versions of the same test can be
+generated automatically, with the ordering of questions within each section
+randomly permuted so as to minimize cheating; the generated answer keys can be
+constructed either with or without the questions included; environments are
+provided to assist in constructing the most common types of test question:
+matching, true/false, multiple-choice, fill-in-the-blank, and short
+answer/essay questions.")
