The six infix comparison operators can each be overloaded separately.  To
overload only ==, define

   def __eq__(self, other):
       # return true or false, depending on whether you think
       # self is equal to other

Note that you need to overload each one you intend to use!  There are no
assumed relationships among them.  For example, if you define __eq__, it
won't be called if the comparison operator is != (there's no assumption that
"x != y" gives the same result as "not x == y", so if you want to affect the
result of !=, you have to supply a __ne__ method too).
