:: Purpose: Allows you to quickly change your IP address without using the GUI
:: Requirements: Windows XP or Vista
:: History: 3.1 Removed warning, fixed error when deleting temp file
:: 3.0 Major re-write:
:: -- Script now supports command-line invocation, with [optional] name of adapter to be changed
:: -- Combined both scripts into one, and added warning to the beginning
:: -- Script can now be invoked with adapter name to be changed. If not it will prompt for it.
:: -- Re-wrote entire menu structure and added new options (DHCP, Quit)
:: -- Cleaned up code to use %TEMP% variable for storing the working text files instead of C:\
:: -- Script now offers to use the OpenDNS servers as backup to the default gateway (for DNS)
:: 2.0 Changed hard-coded adapter name to a script-wide variable and cleaned up menus
:: 1.5 Created basic (ugly) menu structure
:: 1.0 Initial write
::::::::::::::::::::::::::::::::::::::::::::
:: Initialize variables & check arguments ::
