 *
 * RPNIFS comes with a python extension module allowing to use the RPN
 * expressions in python.
 *
 * @ref python_pyrpn.c and @ref python_rpnexpr.c should be compiled in a .so file
 * in order to expose a pyrpn Python module.
 *
 * This module contains functions :
 * - pyrpn.get_ops() returning a dict with long & short operations
 * - pyrpn.random_expr(args_count, token_count=10) generating a random expression
 *
 * And it contains the pyrpn.RPNExpr class with following methods :
 * - pyrpn.RPNExpr.__init__(self, expression, args_count, stack_size=16)
 * - pyrpn.RPNExpr.eval(self, ...) expression evaluation
 * - pyrpn.RPNExpr.reset_stack(self) to set all stack items to 0
