[Mailman-Users] Change nomail property through script?

Hello

I have a quick question, was wondering how I could change user settings (such as nomail to 1) from a script or command line utility rather than the web interface? I am using Mailman version 2.1.4-1. I looked in /var/mailman/bin directory, none of the utilities there appear to be able to do this, the list_members script seems useful for getting a list of users who have nomail set to 1 though.

Does anyone have any ideas on how I can do it?

Thanks

Regards Geoff
