  A number of SysV or ncurses functions don't have wrappers yet; if you
  need a given function, add it and send a patch.  See
  http://www.python.org/dev/patches/ for instructions on how to submit
  patches to Python.

  Here's a list of currently unsupported functions:

  tgetent tgetflag tgetnum tgetstr tgoto timeout tputs
  vidattr vidputs waddchnstr waddchstr
