Biscuits MVC Framework comes with a set of PHP classes for all the standard functionality required for a web site. The core system can be extended by developing your own classes. Your new bespoke classes may reference the core but the core classes should not reference any bespoke add on classes.
When you download and install Biscuits on your own server, you will get all the following core classes, covering basic membership login and social chat with blogs and news post comments.
Some of these classes contain content views and others are tools used to develop views.
