+OTHER PROTOCOLS
+
+Those four classes are operators that give verify algebraic properties
+of other operators. The more their outputs are close to zero, the more
+those other operators are faithful to an algebraic property.

+TESTS AND RULES
+
+For each class, a test file's name is the class name followed by "-test.pd",
+and a rule file's name is the class name followed by "-rule.pd",
+in the same way as it is for help files.
