== Packages and Classes ==
The classes in the {{jf}} are loosely grouped into several different packages, listed below.  The links will take you to further information about each class including, where possible, examples of use.  You can also browse the Joomla Framework and included libraries on [http://api.joomla.org api.joomla.org] which is automatically generated by the phpDocumentor package from an analysis of the Joomla! source code, making use of specially formatted comments embedded in the source code itself.  These two resources, one manually maintained, the other automatic, are intended to complement one another.
