Source Code
xPL is an open protocol, which can be used in either commercial or open source projects and products.
The various utilities, applications and frameworks written by our developers have been released under the GPL, L-GPL and various other licences (mostly open source).
We want people to be able to use and re-use the tools that we have developed, so have placed the source code for all of the applications and tools (which have a compatible licence) in google code.
The Project page is here: http://code.google.com/p/xplproject/
and the path to use in your subversion client is: http://xplproject.googlecode.com/svn/
