  22  * "modules" {
  23  *     "memoserv" {
  24  *         "bot" "NickServ";
  25  *         "message_expiry" "30d"; // age when messages are deleted; set
  26  *                                 // to 0 to disable message expiration
  27  *     };
  28  *  };
  29  *
  30  * After that, to make the module active on an existing bot:
  31  * /msg opserv bind nickserv * *memoserv.*
  32  *
  33  * If you want a dedicated MemoServ bot, make sure the service control
  34  * commands are bound to OpServ:
  35  * /msg opserv bind opserv service *modcmd.joiner
  36  * /msg opserv bind opserv service\ add *modcmd.service\ add
  37  * /msg opserv bind opserv service\ rename *modcmd.service\ rename
  38  * /msg opserv bind opserv service\ trigger *modcmd.service\ trigger
  39  * /msg opserv bind opserv service\ remove *modcmd.service\ remove
  40  * Add the bot:
  41  * /msg opserv service add MemoServ User-to-user Memorandum Service
  42  * /msg opserv bind memoserv help *modcmd.help
  43  * Restart srvx with the updated conf file (as above, butwith "bot"
  44  * "MemoServ"), and bind the commands to it:
  45  * /msg opserv bind memoserv * *memoserv.*
  46  * /msg opserv bind memoserv set *modcmd.joiner
