+# _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.
