jCore

Update: 0.2 major release, changes include additional features, important security and bug fixes, also New shopping (E-commerce) module with instant Paypal payment, Template editor in the admin with a file manager and more! jCore is a Web Content Management System build especially for Webmasters (using the well known LAMP environment) who have to maintain multiple Websites for their clients and would like to keep the source codes up to date and easily fix bugs for all clients at once. It has two main systems: jCore Server, which holds all the libraries and modules you can build on, and jCore Client, which is the stripped version of the core system without any libraries (as it uses the ones from the core).
