py.io
=======
The 'py' lib provides helper classes for capturing IO during
execution of a program.
IO Capturing examples
===============================================
``py.io.StdCapture``
---------------------------
Basic Example::
>>> import py
>>> capture = py.io.StdCapture()
>>> print "hello"
>>> out,err = capture.reset()
>>> out.strip() == "hello"
True
For calling functions you may use a shortcut::
>>> import py
>>> def f(): print "hello"
>>> res, out, err = py.io.StdCapture.call(f)
>>> out.strip() == "hello"
True
``py.io.StdCaptureFD``
---------------------------
If you also want to capture writes to the stdout/stderr
filedescriptors you may invoke::
>>> import py, sys
>>> capture = py.io.StdCaptureFD(out=False, in_=False)
>>> sys.stderr.write("world")
>>> out,err = capture.reset()
>>> err
'world'
