Comment(by darrylwally):

 My experience is that data written to the console via the system stdout
 and stderr cannot be captured by Python as reassigning the stdout/stderr
 in Python does not reassign the stdout/stderr from compiled extensions
 (C/C++, Fortran), see the following threads:

 http://mail.python.org/pipermail/tutor/2003-March/021225.html

 http://wxpython-users.1045709.n5.nabble.com/redirect-message-from-python-
 extension-td2368064.html

 It looks like the the only way to redirect the stdout within the
 extensions themselves via PySys_WriteStdout.  I'm not sure how to handle
 this with the wrapped fortan code.

 The other issue I have is that Intel Fortran coughs and complains when
 setting the iprint>0 if no console is displayed on the screen (i.e. via a
 Windows program).
