[SciPy-user] missing fopen?

Hi,

I am just getting started with scipy (using 0.5.2), and I need to  
read large amounts of fortran77 unformatted data that comes out of  
our simulation code. Searching the web, it appears there used to be a  
class called fopen which had some fort_read methods which would do  
what I need. However, the source for this info is several years old.  
If I do a

import scipy.io
help(scipy.io)

I get a hopeful message about fopen, but it doesn't seem to exist:

In [2]: test = scipy.io.fopen('test.dat')
------------------------------------------------------------------------ 
---
exceptions.AttributeError                            Traceback (most  
recent call last)

/Users/joishi/<ipython console>

AttributeError: 'module' object has no attribute 'fopen'

Additionally, grepping through Lib/io/numpyiomodule.c seems to reveal  
nothing about fopen. Has it been expunged from scipy? If so, is there  
any way to read f77 unformatted binary?

thanks,

j
