[Mailman-Users] How can I get an ascii dump of the mailman users list for a backup?

[Robin McCain]

I need to backup my mailman database and do some user maintenance - how 
can I get a .csv file or something similar so I can compare the present 
list to the list I entered 6 months ago? I tried to install Mailman 
using MySQL so this would be easy to do, but it ignored MySQL and 
created its own database.

Are there any tools to extract statistical data out of the mailman database?
