  This module provides an easy way to enable importing a package event
  if it's not on sys.path. The main use case is to import a package 
  from its developmment repository without having to install it.
  
  This module is sort of like a symlink for Python modules.
  
  To install: 
    1) Copy this file to a directory that is on the PYTHONPATH
    2) Rename the file to "yourpackage.py".
  
  If the real package is in "yourpackage/yourpackage" relative to this file, 
  you're done. Otherwise modify PARENT_DIR_OF_MODULE.
