    RSS Event Manager

    Allows you to submit events to an RSS feed via rest api (http post)

    This tool was originally written to replace the massive amounts of email sent out by automated build scripts. Once this tool is deployed to a server, your scripts can simply use a HTTP Post to submit events, and users can subscribe to the RSS feed to receive updates, instead of receiving an email for each event. It is trivial to add a new feed, and using http to submit events means that firewalls are (usually) not a concern.
