Zaapt is a CMS written in Perl/Mason and using PostgreSQL as it's database. It includes many content types (managed pages, news, blogs, forums, etc) which can be used straight out of the box.

The example sites include:

• minor customisations with an admin area - Zaapt Homepage
• minimal customisations - Zaapt Homepage (Simple)
• major customisations (*)
• a standalone administration site (*)

(Note: * these sites are yet to be added.)
