Sputnik is a content management system (CMS)
designed for extensibility. It works as a wiki out
of the box, but can be extended into other things.
It offers editable nodes, history and diff, user
accounts with optional email validation, a
flexible permission system, RSS feeds, and more.
Sputnik supports access control and has editable
templates. It can be used to maintain a personal
Web site that doesn't look like a wiki and that
only you can edit. Sputnik is easy to install on
shared hosting without root accounts.
