the package, and perhaps a particular module inside it.

# _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.
