-# DEPRECATED by load block on extras palette.
-
-# This procedure is invoked when the user-definable block on the
-# "extras" palette is selected.
-
-# Usage: Import this code into a Python (user-definable) block; when
-# this code is run, the turtle will create a block at the current
-# location of the turtle. The first argument to the Python block
-# should be a string containing the name of the desired
-# block. Arguments to the block can be passed by expanding the Python
-# block to include up to two additional arguments. Note that the
-# turtle is moved to the bottom of the block after it is loaded in
-# order position another block to the bottom of the stack.
-
-# The status of these blocks is set to 'load block'
-
-# For example, try the following to place forward 100, right 90 on the canvas:
-# start
-# Python(forward, 100) <-- Python load_block.py expanded to two arguments
-# Python(right, 90) <-- Python load_block.py expanded to two arguments
