Description:

ListGarden is a tool for manually creating and maintaining RSS
feeds. It is an easy to use open source authoring tool operated with
a browser interface that can run locally on a computer running Windows,
Mac OS X, or Linux, or accessed remotely through a web server. The
resulting XML file may be stored locally or automatically copied to a
remote web server using FTP. It is useful for RSS feeds that need to be
maintained without an automatic system that has built-in RSS generation
capability. It can be used for RSS feeds that are change logs, event
lists, lists of physical objects, or post lists of podcasts and
manually authored weblogs.
