Deleting users from command line or syncing with Duncan's plugin


i am using the great plugin from Ducan Cameron to import csv files to php list and it works like a charm but… is there a way to delete suscribers from a list as well with command line?

my target is to sync phplist suscribers and the csv files daily… but if i delete a user from the csv list, that user is never deleted from the suscribers list
