# pagebbox.py
#-----------------------------------------------------------
# Python script which creates a function "pagebbox(width, height)"
# that generates a bounding box of the specified width and height.
#
# Execute this script using menu option "File/Execute Script",
# if Python has been compiled in.
#
# Add key 'B' for popuppromt asking for page size.  Add button to
# "Edit" menu for same.  Add Ctrl-B and Ctrl-Shift-B for standard
# 8 1/2 x 11 and 11 x 17 page bounding boxes.
