I agree that the flag would be more pythonic in dbf.py.

I was not aware that you are adding sqlite functionality to your
library. This is very cool!

I have been through the same questions with my own DBF library, and
I've come to some conclusions: First, I decided to make the library
read-only and in-memory. That is all we need in-house anyway. Second,
I decided to make an external tool for converting DBF files to sqlite:

  https://github.com/olemb/dbfget/blob/master/extras/dbf2sqlite

(To anyone reading: I have not yet made a public announcement of
dbfget, but I will shortly. Consider this an informal announcement:
https://github.com/olemb/dbfget/ )

I am considering adding a "streaming=True" flag which would make the
table class a record generator, and a "save()" method which would
allow you to save data back to the file, or to a new file if you
provide an optional file name. In fact, I had this functionality in
earlier versions, but decided to chuck it out in order to make the API
as clean as possible.

I hope this can help you somehow in your decision making process.
