[capi-sig] How to assign docstring for built-in methods?

[Subhasis Ray]

Hi,
 I am trying to figure out if I can pass a custom docstring for builtin
methods like tp_init of my C extension class. I tried method tables, but
that does not work for these special methods. Python puts some
documentation automatically which I want to override with the correct
parameter descriptions etc:

__init__(...)
      x.__init__(...) initializes x; see help(type(x)) for signature


 I tried asking this in more generic forums, but got no authoritative
answer.

Thanks,
  Subha
