The mailing list for listmasters using Sympa

[Mark London <address@concealed>]

Hi - I'm trying to convert from mailman to sympa.  Is there a way to add 
a user to a mailing list, from the command line?

Mailman has a script that allows me to subscribe a user to a mailing 
list, from the command line.

I use this feature, in order to easily add a user to multiple mailing 
lists, without having to use the web interface.

Is there a similar feature in sympa?   Or would I need to create an 
email, sent from the list owner's email address, with an "ADD" command 
for each mailing list?

Thanks. - Mark
