Comb is a modular weblog/website engine.

A Comb site consists a single *database*,
accessed through multiple *interfaces*:

 - Web interface
 - Atom/RSS interface
 - Administration interface
 - XML-RPC interface

These are all interfaces to the underlying database.
They are implemented in Comb as Ruby classes,
all of which inherit from a super-class,
which serves as a general-purpose interface to the database.

Comb is customized and extended by editing the interfaces.
For example, the web interface replaces the "themes"
characteristic of most other content management systems.
