Drupal is a free software package that allows an individual or a community of users to easily publish, manage and organize a wide variety of content on a website. Tens of thousands of people and organizations are using Drupal to power scores of different web sites. The standard release of Drupal, known as Drupal core, contains basic features common to most CMSs. These include the ability to register and maintain individual user accounts within a flexible and rich permission / privilege system, create and manage menus, RSS-feeds, customize page layout, perform logging, and administer the system. As installed, Drupal provides options to create a classic brochureware website, a single- or multi-user blog, an Internet forum, or a community website providing for User-generated content. Drupal was also designed to allow new features and custom behavior to be added to extend Drupal\'s core capabilities. This is done via installation of plug-in modules (known as contrib modules) created and contributed to the project by open source community members. For this reason, Drupal is sometimes described as a content management framework. Although Drupal offers a sophisticated programming interface for developers, no programming skills are required for basic website installation and administration.
