YaWPS (Yet another Web Portal System) is a hybrid between a content management system and a web portal for medium- or small-sized Internet- or Intranetsites.
All system maintainance is done via a webinterface, so no special tools are needed for administrators or moderators. All client output is valid HTML4.
YaWPS works on most common UNIX platforms as well as on Windows platforms.
