Drupal is free content-management software designed to let an individual or user group publish, manage and organize Web sites that feature a wide variety of content. Drupal is currently being used to power community Web portals, discussion sites, corporate Web sites, intranet applications, personal Web sites and blogs, fan sites, e-commerce applications, resource directories and social networking sites. Recently, the Obama administration adopted Drupal as the foundation for the WhiteHouse.gov Web site.
