   4  * CMDNAME: permban
   5  * CMDLEVEL: QCMD_AUTHED
   6  * CMDARGS: 3
   7  * CMDDESC: Permanently bans a hostmask on a channel.
   8  * CMDFUNC: csc_dopermban
   9  * CMDPROTO: int csc_dopermban(void *source, int cargc, char **cargv);
  10  * CMDHELP: Usage: PERMBAN <channel> <hostmask> [<reason>]
  11  * CMDHELP: Permanently bans the provided hostmask on the channel.  If the ban is
  12  * CMDHELP: removed from the channel e.g. by a channel op or the BANTIMER feature, the
  13  * CMDHELP: ban will be reapplied if a matching user joins the channel.  Bans
  14  * CMDHELP: set with the PERMBAN command can be removed via BANCLEAR or BANDEL.  Any users
  15  * CMDHELP: matching the hostmask will be kicked from the channel.
  16  * CMDHELP: Where:
  17  * CMDHELP: channel  - channel to set a ban on
  18  * CMDHELP: hostmask - hostmask (nick!user@host) to ban.
  19  * CMDHELP: reason   - reason for the ban.  This will be used in kick messages when kicking
  20  * CMDHELP:            users matching the ban.  If this is not provided the generic message
  21  * CMDHELP:            \"Banned.\" will be used.
  22  * CMDHELP: PERMBAN requires master (+m) access on the named channel.
