'''login -- PythonWin user ID and password dialog box

(Adapted from originally distributed with Mark Hammond's PythonWin - 
this now replaces it!)

login.GetLogin() displays a modal "OK/Cancel" dialog box with input
fields for a user ID and password. The password field input is masked
with *'s. GetLogin takes two optional parameters, a window title, and a
default user ID. If these parameters are omitted, the title defaults to
"Login", and the user ID is left blank. GetLogin returns a (userid, password)
tuple. GetLogin can be called from scripts running on the console - i.e. you
don't need to write a full-blown GUI app to use it.

login.GetPassword() is similar, except there is no username field.

Example:
import pywin.dialogs.login
title = "FTP Login"
def_user = "fred"
userid, password = pywin.dialogs.login.GetLogin(title, def_user)
