src/vrpn/README.python

-python_vrpn:
-	VRPN wrapped in Python using Swig.  Works with Python 2.7.
-
-python:
-	Hand-written Python classes that work with Python 2.7 and 3.2.
-	Compile the main library (ie.: root of VRPN) and the quat library.  Then, go to the "python" folder. Before making the binary, you have to define the "PYTHON_VERSION" environment variable to the version of python you want to compile it for (ie.: "3.2", "2.7" ...).  And you have to put the resulting vrpn.so shared library (found in $HW_OS/$PYTHON_VERSION) in the python module folder or in a path defined in the PYTHONPATH environment variable.
-
-	The "essai_*.py" are simple python files that show you how to use this module (the single difference is a call to python3.2 or python2.7 interpreter).

src/vrpn/android_widgets/README.txt

-This project is totally distinct from java_vrpn and the Vrpn server running on Android.
-
-The Vrpn widgets for Android provide a set of Android Widgets that are bound to a Vrpn server. On the Android device, an application can be written mainly with Android XML layout, almost without Java coding. The documentation of the widgets is in android_widgets/vrpn_library/doc/
-
-The Android application will send updates as UDP packets with a JSON payload to the vrpn_Tracker_JsonNet device. You need a VRPN server build with VRPN_USE_JSONNET and a vrpn.cfg file that declares a vrpn_Tracker_JsonNet device.
-
-To build such a server you need JSONCPP. See README.jsoncpp for instructions about obtaining and building JSONCPP first, then use CMAKE to generate the VRPN project with VRPN_USE_JSONNET. You will need to define the JSONCPP_ROOT_DIR CMake variable.
-
-Note : 
-	the JSONNET server was built and tested only on Windows 7 32 bits, MSVC 2008
