It took me a while to track it down, but there used to be a module/file 
called 'convertcode.py' for conversion. It was mentioned as tip in 
Travis's 'Guide to Numpy'  page 31 in Jan 6 2005 version. But the 
alter_code path is in Dec 7 2006 (linked at http://docs.scipy.org/doc/). 
It is advisable to read it as it address differences between Numeric and 
old numpy ie section 2.6!

Travis said in the thread: 
"The transition approach is to use the compatibility layer first by 
running oldnumeric.alter_code1.py and then running  alter_code2.py which 
will take you from the compatibility layer to NumPy  (but alter_code2 is 
not completed yet)."
