"""
This is a little script I wrote to convert my gmail contacts into this
address-book format. I don't know whether gmail's format is constant over time,
and this is not something that needs to be done repeatedly. Thus I write it as a
sample one-off script.

In order for this to work, I exported gmail's contacts as a csv. I save the
resulting addressbook in the local directory and append it to my systemwide
addressbook afterwards (it would be easy to generate it directly, but this
is sufficient for a one-off script).

I suggest running the addressbook through uniq once afterwards.
