My latest contribution to the Sympa listserv tool documentation is on the Contribs site:
* Create a new list
* Add a new list to an existing family
* Instantiate a new family, or update changed settings on a family
* Remove a list, keeping an archive
* Remove a list completely
* Automate customization of footer
Sample xml file, family xml template, and footer files. This tool helped me create multiple lists quickly and modify families, which I found sometimes to be more complicated than they needed to be. Following the list of procedures in this script helped me better understand what Sympa needs to do for list maintenance.
