	# == Description
	# Provides your Ruby scripts with a generic Exception Dialog.  The dialog
	# is invoked by a .Net executable (called dialog.exe).  This reduces the
	# requirements on custom widgets sets as Ruby gems.

		# Show an exception dialog for the specified exception; message, 
		# author and email are optional but highly recommended.
