Text is error message.
A line of data in an output block. The text is a prompt to be displayed to the user, asking for a string. In addition, though normally each key can only have a single value tied to it, sub-keys can be grouped into a list which can be assigned to a single key. The set of commands is designed to be fairly generic and yet fairly comprehensive, so as not to tie it to any one mailing list package. This should allow it to work for Lyris, or Majordomo, or Listserv, or Petidomo, or Listar.
