Hackable, download-free demos/tutorials are out.
These simple demonstrations of common active tags--<if>, <repeat>, <include>, and more--not only execute live for you, but allow you to modify and re-process the "source document" to get an instant hands-on feel for a radical (and radically simple) new web language. No need to download anything; try it now, and you'll be running your own PIA "programs" in minutes!

7/12/99 Our CVS server is now online at cvs.risource.org
We use CVS (Concurrent Versions System) for version control of the source code and documents. The most recent updates can be retrieved with any CVS client (version 1.10 or higher) from our server. See the CVS page for more details.

Conforming examples
All XML pages that comprise the example applications now more closely conform to the XML specification. In particular, all tags are now properly closed and attribute values are quoted. Note that the process command in PIA/bin/ can be used to "clean-up" hand edited XML.
