\n\
This module exports a set of functions implemented in C corresponding\n\
to the intrinsic operators of Python. For example, operator.add(x, y)\n\
is equivalent to the expression x+y. The function names are those\n\
used for special class methods; variants without leading and trailing\n\
'__' are also provided for convenience.");
