"""curses

The main package for curses support for Python.  Normally used by importing
the package, and perhaps a particular module inside it.

# Some constants, most notably the ACS_* ones, are only added to the C
# _curses module's dictionary after initscr() is called.  (Some
# versions of SGI's curses don't define values for those constants
# until initscr() has been called.)  This wrapper function calls the
# underlying C initscr(), and then copies the constants from the
# _curses module to the curses package's dictionary.  Don't do 'from
# curses import *' if you'll be needing the ACS_* constants.
