SiteExporter is a command-line Java program that is run hourly (currently at 20 19 minutes after the hour) from Apache's BuildBot. It makes a web service call to Confluence (to its RSS feed, actually) to get a list of pages that have changed since the last run, and the HTML-formatted export of those pages. For each, it post-processes the file (described below). Finally, SiteExporter commits all changed HTML files into Tapestry's part of the Apache Subversion repository, which (nearly instantly) makes it available to the public at http://tapestry.apache.org, and commit emails are sent to Tapestry's "commits" mailing list.

The time between saving a change in Confluence and seeing the result on the public site is at most 1 hour, depending on when you do it. If you save a change at 19 18 minutes after the hour you'll see the change in about a minute. If you publish it at 21 20 minutes after the hour then you'll have to wait almost an hour.
