+# Blender.BGL module (OpenGL wrapper)
+
+"""
+The Blender.BGL submodule
+
+This module wraps OpenGL constants and functions, making them available from
+within Blender Python.  The complete list can be retrieved from the module
+itself, by listing its contents: dir(Blender.BGL).  There are too many to be
+documented here, but a simple search on the net can point to more than enough
+material to teach OpenGL programming, from books to many collections of
+tutorials.  The I{red book}: "OpenGL Programming Guide", is a very good
+resource, even for newcomers.
+@see: U{www.opengl.org}
+
+Example::
+ import Blender
+ from Blender.BGL import *
+ from Blender import Draw
+ R = G = B = 0
+ A = 1
+ instructions = "Hold mouse buttons to change the background color."
+ quitting = " Press ESC or q to quit."
+ #
+ def show_win():
+  glClearColor(R,G,B,A)                # define color used to clear buffers 
+  glClear(GL_COLOR_BUFFER_BIT)         # use it to clear the color buffer
+  glColor3f(1,1,1)                     # change default color
+  glRasterPos2i(50,100)                # move cursor to x = 50, y = 100
+  Draw.Text("Testing BGL  + Draw")     # draw this text there
+  glRasterPos2i(350,20)                # move cursor again
+  Draw.Text(instructions + quitting)   # draw another msg
+  glBegin(GL_LINE_LOOP)                # begin a vertex-data list
+  glVertex2i(46,92)
+  glVertex2i(120,92)
+  glVertex2i(120,115)
+  glVertex2i(46,115)

+  glColor3f(0.35,0.18,0.92)            # change default color again
+  glBegin(GL_POLYGON)                  # another list, for a polygon
+  glVertex2i(315, 292)
+  glVertex2i(412, 200)
+  glVertex2i(264, 256)
+  glEnd()
+  Draw.Redraw(1)                       # make changes visible.
+ #
+ def ev(evt, val):                     # this is a callback for Draw.Register()
