PyJuggler is distributed from the VR Juggler SourceForge.net project site. Because PyJuggler is still in the developmental stages, it is recommended that users keep up to date with the latest version at all times. PyJuggler will always keep up to date with the VR Juggler API, and because it provides a one-to-one mapping of C++ to Python, the API will be identical except for slight differences based on Python syntax.
PyJuggler is an open source software library, and as such, its source code is available. Users are free to download the source, look at it, and modify it (keeping in mind the requirements of the license, of course). For the most part, the PyJuggler source code is pretty dull; the interesting aspect is what developers can do to write VR Juggler application objects in Python. As such, the source is provided primarily so that people can compile it for their local hardware and operating system. Some pre-compiled binary versions will exist, but the requirements of those binaries may not satisfy every single user's needs.
