# Usage: Import this code into a Python (user-definable) block; when
-# this code is run, the turtle will draw a line of the length of the
-# numeric argument block docked to the Python block. But before
-# drawing the line, it pushes the rgb values of the destination to the
-# FILO.
+# this code is run, a new block will be added to the Turtle Palette.
+# This block will be named 'name', the value of the argument block
+# docked to the Python block.

+# The new block will cause the turtle to draw a line of the
+# length. But before drawing the line, it pushes the rgb values of the
