Just wanted to say this is great news!
I added my own pyf interface descriptions for two of the arpack
functions to the tracker.  May not be of much use to you, but thought
I'd put it up there for comparison.  I'm no f2py expert, though (nor
am I an 'f' expert, or a 'py' expert for that matter :-) )  But I've
been using the wrapper with my pyf for a while without issues.
