Demonstration of communication with external code
=================================================

C'est no pas un pipe.

text-based standard IO
======================
pipe.f90
pipe.py


compile
-------
on command line:

   gfortran pipe.f90 -o pipe


use
---
in python:

   from pipe import Call
   c = Call()
   c([3, 4])
   c([3, 5])
   del c

the last line kills te process.


pipe-based binary IO
====================
pipe2.f90
pipe2.py


compile
-------
on command line:

   gfortran pipe2.f90 -o pipe2

use
---
in python:

   from pipe2 import Call2
   c = Call2()
   c([3, 4])
   c([3, 5])
   del c

the last line kills te process and deletes the pipes.

One may spcify the parameter 'verbose=True'

   c = Call2(verbose=True)

f2p module-based communication
==============================

use
---
in python

   from pipe3 import Call3
   c = Call3()
   c([3, 4])
   c([3, 5])


This automatically compiles to a binary module and loads it.
The module is just loaded in python and does not need to be terminated.
