It must already exist.
OPTIONS
-n file, --non-digest-members-file file
A file containing addresses of the members to be added, one address per line. This list of people become
non-digest members. If file is `-', read addresses from stdin.
-d file, --digest-members-file file
Similar to above, but these people become digest members.
-c [y|n], --changes-msg [y|n]
Whether or not to send the list members the `there's going to be big changes to your list' message.
defaults to no.
-w [y|n], --welcome-msg [y|n]
set whether or not to send the list members a welcome message, overriding whatever the list's `send_wel-
come_msg' setting is.
-h, --help
Print a help message and exit.
NOTES
You must supply at least one of -n and -d options. At most one of the files can be `-'.
