# This also works for directories directly under the current
# directory. However to make it work you need a file
# in the 'dir1' directory called __init__.py
# (That file can be empty... it is there to tell Python: this is 
# a directory of Python modules)
#
# Using this method you must use dot notation to import like I've 
# done below.
#
# See http://docs.python.org/tut/node8.html
