Guido van Rossum 716a89c606 Patch by Charles Waldman to implement an optional nlines argument to 
w.scroll().  (It then calls wscrl(win, nlines) instead of scoll(win).)

/******************************************************************
This is a curses implementation. I have tried to be as complete
as possible. If there are functions you need that are not included,
please let me know and/or send me some diffs.
There are 3 basic types exported by this module:
1) Screen - This is not currently used
2) Window - This is the basic type. This is equivalent to "WINDOW *".
3) Pad - This is similar to Window, but works with Pads as defined
in curses.
Most of the routines can be looked up using the curses man page.
Here is a list of the currently supported methods and attributes
in the curses module:
Return Value Func/Attr Description
--------------------------------------------------------------------------
StringObject version A string representing the current
version of this module.
WindowObject initscr() This initializes the screen for use
None endwin() Closes down the screen and returns
things as they were before calling
initscr()
True/FalseObject isendwin() Has endwin() been called?
None doupdate() Updates screen
WindowObject newwin(nlines,ncols,begin_y,begin_x)
newwin(begin_y,begin_x)
newwin() creates and returns
a new window.
None beep() Beep the screen if possible
None flash() Flash the screen if possible
None ungetch(int) Push the int back so next getch()
will return it.
Note: argument is an INT, not a CHAR
None flushinp() Flush all input buffers
None cbreak() Enter cbreak mode
None nocbreak() Leave cbreak mode
None echo() Enter echo mode
None noecho() Leave echo mode
None nl() Enter nl mode
None nonl() Leave nl mode
None raw() Enter raw mode
None noraw() Leave raw mode
None intrflush(int) Set or reset interruptable flush
mode, int=1 if set, 0 if notset.
None meta(int) Allow 8 bit or 7 bit chars.
int=1 is 8 bit, int=0 is 7 bit
StringObject keyname(int) return the text representation
of a KEY_ value. (see below)
Here is a list of the currently supported methods and attributes
in the WindowObject:
Return Value Func/Attr Description
--------------------------------------------------------------------------
None refresh() Do refresh
None nooutrefresh() Mark for refresh but wait
None mvwin(new_y,new_x) Move Window
None move(new_y,new_x) Move Cursor
WindowObject subwin(nlines,ncols,begin_y,begin_x)
subwin(begin_y,begin_x)
None addch(y,x,ch,attr)
addch(y,x,ch)
addch(ch,attr)
addch(ch)
None insch(y,x,ch,attr)
insch(y,x,ch)
insch(ch,attr)
insch(ch)
None delch(y,x)
delch()
None echochar(ch,attr)
echochar(ch)
None addstr(y,x,str,attr)
addstr(y,x,str)
addstr(str,attr)
addstr(str)
None attron(attr)
None attroff(attr)
None attrset(sttr)
None standend()
None standout()
None border(ls,rs,ts,bs,tl,tr,bl,br) (accepts 0-8 INT args)
None box(vertch,horch) vertch and horch are INTS
box()
None hline(y,x,ch,n)
hline(ch,n)
None vline(y,x,ch,n)
vline(ch,n)
None erase()
None deleteln()
None insertln()
(y,x) getyx()

Change Log:
Version 1.2: 95/02/23 (Steve Clift)
Fixed several potential core-dumping bugs.
Reworked arg parsing where variable arg lists are used.
Generate exceptions when ERR or NULL is returned by curses functions.
Changed return types to match SysV Curses manual descriptions.
Added keypad() to window method list.
Added border(), hline() and vline() window methods.
Version 1.1: 94/08/31:
Minor fixes given by Guido.
Changed 'ncurses' to 'curses'
Changed '__version__' to 'version'
Added PyErr_Clear() where needed
Moved ACS_* attribute initialization to PyCurses_InitScr() to fix
crash on SGI
Version 1.0: 94/08/30:
This is the first release of this software.
Released to the Internet via python-list@cwi.nl
