Module implementing utilities to get a password and/or the current user name.

getpass(prompt) - prompt for a password, with echo turned off
getuser() - get the user name from the environment or password database

This module is a replacement for the one found in the Python distribution. It
is to provide a debugger compatible variant of the a.m. functions.
