"""This is an example script for the py/pyext object's buffer support.

PD/Max buffers can be imported to and exported from numarray arrays.
For numarray see http://numeric.scipy.org
It will probably once be replaced by Numeric

- _import(buffer): copy contents from the buffer to a new numarray object
- _export(buffer,numarray): export contents of numarray object to the buffer
