# Clear-screen and error beep module for various platforms.
# ---------------------------------------------------------
#
# File saved as "clsbeep.py" and placed into the Python - Lib drawer or
# where-ever the modules are located.
#
# Setting up a basic error beep and clear screen for Python 1.4 and greater.
# (Original idea copyright, (C)2002, B.Walker, G0LCU.)
#
# Issued as Public Domain and you can do with it as you please.
#
# Tested on Python 1.4.x for a stock AMIGA 1200 and Python 2.0.x for WinUAE.
# Tested on Python 2.4.2 for Windows ME and Python 2.6.2 for XP-SP2.
# (Now changed to include Windows Vista, [and Windows 7?], to Python 2.7.x)
# Tested on Python 2.5.2 for PCLinuxOS 2009, Knoppix 5.1.1 and Python 2.6.6
# on Debian 6.0.0...
# All platforms in CLI/Command-Prompt/Terminal mode.
#
# It is SO easy to convert to Python 3.x that I have not bothered. I`ll leave
# you guys to work that one out... :)
#
# ----------------------
# Usage in other files:-
# >>> import clsbeep[RETURN/ENTER]
# ----------------------
# Called as:-
# clsbeep.beep()
# clsbeep.cls()
# clsbeep.both()
# ----------------------
# The ~if~ statement selects the correct format for the platform in use.

# Import necessary modules for this to work.
