# DESCRIPTION:
#
# Produces the command "pyHelloWorld". 
#
# This is a simple demonstration of how to use a Python plug-in.
# A "Hello World" text is output to the script editor window.
#
# To use, make sure that pyHelloWorldCmd.py is in your MAYA_PLUG_IN_PATH,
# then do the following:
#
#   import maya
#   maya.cmds.loadPlugin("pyHelloWorldCmd.py")
#   maya.cmds.pyHelloWorld()
