Wiki with integrated to-do list and scheduler

 Nurpawiki is a personal information manager (PIM) application that
 combines a wiki, a to-do list and a simple scheduler to help you get
 organized. It aims to ease note taking and action planning. Actions
 (to-dos) are always associated with notes or plans (wiki pages).
 .
 Nurpawiki is available as an Eliom module for the Ocsigen web server,
 and uses PostgreSQL as backend.
