# Usage: python make_book_list
#
# Script to create a list of the books on an Amazon wish list.
# Each line is a list which consists of three items:
#  1/ The book ASIN
#  2/ The current lowest used price.
#  3/ The book title
#
# This list (which is written to a file called "books.py" in the
# current directory) will be used as input to the cheap_books.py script.
# That script only needs the first two items in each list entry.
# The other one is there to help you know which book is which.
#
# Before you run the cheap_books.py script, you will need to adjust
# the current used price values to be the price you are willing to pay
# for that book. In other words, books with a used price below that value 
# will be flagged by the cheap_books.py script.
#
# Uses the pyAmazon Amazon Web Service API wrapper maintained by
