   4  * CMDNAME: bandel
   5  * CMDLEVEL: QCMD_AUTHED
   6  * CMDARGS: 2
   7  * CMDDESC: Removes a single ban from a channel.
   8  * CMDFUNC: csc_dobandel
   9  * CMDPROTO: int csc_dobandel(void *source, int cargc, char **cargv);
  10  * CMDHELP: Usage: BANDEL <channel> <ban>
  11  * CMDHELP: Removes the specified persistent or channel ban, where:
  12  * CMDHELP: channel - the channel to use
  13  * CMDHELP: ban     - either a ban mask (nick!user@host), or #number (see BANLIST)
  14  * CMDHELP: Removing channel bans requires operator (+o) access on the named channel.
  15  * CMDHELP: Removing persistent bans requires master (+m) access on the named channel.
