 To run the tests, type:
 python py-kdtree_test.py
 
+You can customize the data types to create bindings for in the file
+python-bindings/gen-swig-hpp.py:
+
+TREE_TYPES = [(dim, "int", "unsigned long long", "i", "L") for dim in range(2,7)] + \
+             [(dim, "float", "unsigned long long", "f", "L") for dim in range(2,7)]    
+
+This default setup creates 12 bindings. For both int and float
+coordinate data types it creates all versions from 2 to 6
+dimensions. Each point in the space is identified by one unsigned long
+long. This should not be changed. Each tuple in the TREE_TYPES list has the following semantics:
+
+(dimension,
+ C coordinate data type,
+ C payload data type,
+ PyArg_ParseTuple format character to convert the C coordinate data type to Python,
+ PyArg_ParseTuple format character to convert the C payload data type to Python
+)
