minimalistic set of imports/inits to get me running

First  of all thank you a lot for a great product

I want to do some scripting of operations over bibtex files (or may be
some other bibs), but I've confused a bit with what would be the minimal
set of libraries necessary to perform next set of operations in regular
command line interface of python or ipython,

I just want to read bibtex file
Adjust different fields 
save it back to the same or another file.

Using pybliographer as the starter of the script is ok but not
interactive. Blind copying of most of init commands found in
pybliographer helped a bit but not quite... 

Can you please help me? (or it is Friday and I'm asking nonsense? :-))

Sincerely
Yarik
