+Using PyOtherSide with Blackberry 10
+====================================
+
+Blackberry 10 already has Python 3.2.2 installed on-device, but no Qt 5.
+The approach we currently use is:
+
+ - Build Qt 5.1 using the Native SDK
+ - Get a set of matching Python 3.2.2 headers
+ - Fetch the following files from the device's filesystem:
+     /usr/lib/libpython3.2m.so
+     /usr/include/python3.2m/pyconfig.h
+ - Use pyconfig.h with the Python 3.2.2 headers, link against libpython3.2m
+
+A python.pri file could look like this:
+    QMAKE_LIBS += -lpython3.2m -L/path/to/where/the/library/is
+    QMAKE_CXXFLAGS += -I/path/to/where/the/headers/are/include/python3.2m
+
+After installing pyotherside in the locally-build Qt 5.1 (cross-compiled for
+BB10), the QML plugins folder can be deployed with the .bar file.
