extraction tool using CRF++

[cerr]

Hi,

I want to write an extraction tool using CRF++ (http://crfpp.googlecode.com/svn/trunk/doc/index.html).
I have written a trainings file and a template:
training:
banana  FOOD    B-NP
bread   FOOD    I-NP
template:
U01:%x[0,1]
U02:%x[1,1]

and now I want to go ahead and extract the foods from a sentence like "how do I make a banana bread". Also, I'm unsure how I interface to crf++ with python, I compiled and installed it from source as described on the above website but I don't have a crf module available in python...
