This script uses the csv module to convert gmail.com contacts data to the "raw" gnokii phonbook format, which is another CSV variant, while preserving cell/home/work/fax numbers, street address, URL and notes data entries.
gnokii (www.gnokii.org) is an open source program for communicating with mobile phones that runs under Windows and Linux/Unix. Note that gmail.com supports exporting contacts in both Outlook and Gmail CSV formats. This script needs the Gmail format.
