Look in the Pickaxe 1st Ed., in the documentation for the Module class, 
under "Instance Methods." The <, <=, >, >= methods are documented.

"One module is considered greater than another if it is included in (or 
is a parent class of) the other module. The other operators are defined 
accordingly. If there is no relationship between the modules, returns 
false for all operators."
