+
+sprites.py is a simple sprites library for managing graphics objects,
+'sprites', on a canvas. It manages multiple sprites with methods such
+as move, hide, set_layer, etc.
+
+There are two classes:
+
+class Sprites maintains a collection of sprites.
+class Sprite manages individual sprites within the collection.
+
+Example usage:
+        # Import the classes into your program.
+        from sprites import Sprites, Sprite
+
+        # Create a new sprite collection for a gtk Drawing Area.
+        my_drawing_area = gtk.DrawingArea()
+        self.sprite_list = Sprites(my_drawing_area)
+
+        # Create a "pixbuf" (in this example, from SVG).
+        my_pixbuf = svg_str_to_pixbuf("<svg>...some svg code...</svg>")
+
+        # Create a sprite at position x1, y1.
+        my_sprite = sprites.Sprite(self.sprite_list, x1, y1, my_pixbuf)
+
+        # Move the sprite to a new position.
+        my_sprite.move((x1+dx, y1+dy))
+
+        # Create another "pixbuf".
+        your_pixbuf = svg_str_to_pixbuf("<svg>...some svg code...</svg>")
+
+        # Create a sprite at position x2, y2.
+        your_sprite = sprites.Sprite(self.sprite_list, x2, y2, my_pixbuf)
+
+        # Assign the sprites to layers.
+        # In this example, your_sprite will be on top of my_sprite.
+        my_sprite.set_layer(100)
+        your_sprite.set_layer(200)
+
+        # Now put my_sprite on top of your_sprite.
+        my_sprite.set_layer(300)
+
+# method for converting SVG to a gtk pixbuf
+def svg_str_to_pixbuf(svg_string):
+    pl = gtk.gdk.PixbufLoader('svg')
+    pl.write(svg_string)
+    pl.close()
+    pixbuf = pl.get_pixbuf()

+This file contains the constants that by-in-large determine the
+behavior of Turtle Art. Notably, the block palettes are defined
+below. If you want to add a new block to Turtle Art, it is generally a
+matter of modifying some tables below and then adding the primitive to
+talogo.py. For example, if we want to add a new turtle command,
+'uturn', we'd make the following changes:
+
+(1) We'd add 'uturn' to the PALETTES list of lists:
+
+PALETTES = [['forward', 'back', 'clean', 'left', 'right', 'uturn', 'show', 
+             'seth', 'setxy', 'heading', 'xcor', 'ycor', 'setscale',
+              'arc', 'scale'],
+            ['penup','pendown', 'setpensize', 'fillscreen', 'pensize',...
+
+(2) Then we'd add it to one of the block-style definitions. Since it takes
+no arguments, we'd add it here:
+
+BASIC_STYLE = ['clean', 'penup', 'pendown', 'stack1', 'stack2', 'vspace',
+    'hideblocks', 'showblocks', 'clearheap', 'printheap', 'kbinput', 'uturn']
+
+(3) Then we give it a name (Note the syntax _('string to be
+translated') used by the language-internationalization system; also
+note that the name is an array, as some blocks contain multiple
+strings.):
+
+BLOCK_NAMES = {
+...
+    'uturn':[_('u-turn')],
+...
+              }
+
+(4) and a help-menu entry:
+
+HELP_STRINGS = {
+...
+    'uturn':_('change the heading of the turtle 180 degrees'),
+...
+               }
+
+(5) Next, we need to define it as a primitive for the Logo command
+parser (generally just the same name):
+
+PRIMITIVES = {
+...
+    'uturn':'uturn',
+...
+             }
+
+(6) Since there are no default arguments, we don't need to do anything
+else here. But we do need to define the actual function in talogo.py
+
+DEFPRIM = {
+...
+    'uturn':[0, lambda self: self.tw.canvas.seth(self.tw.canvas.heading+180)],
+...
+          }
+
+That's it. When you next run Turtle Art, you will have a 'uturn' block
+on the Turtle Palette.
+
+Adding a new palette is simply a matter of: (1) adding an additional
+entry to PALETTE_NAMES; (2) new list of blocks to PALETTES; and (3) an
+additional entry in COLORS. However you will have to: (4) create icons
+for the palette-selector buttons. These are kept in the icons
+subdirectory. You need two icons: yourpalettenameoff.svg and
+yourpalettenameon.svg, where yourpalettename is the same string as the
+entry you added to the PALETTE_NAMES list. Note that the icons should
+be the same size (55x55) as the others. This is the default icon size
+for Sugar toolbars.
