UPGRADE NOTICE - PLEASE READ
======================================================================

0.2 - 2008-29-09
----------------------------------------------------------------------
- BREAKING API: Removed category from the module. It didn't fit the way 
  I wanted to handle the resulting array with configuration values. So
  you cannot use this as long as you have two or more variables of the
  same name with another category. Also, function calls need to be
  updated.
- Added support for Sugar external cache
- Added comments on the functions
