27 /* $ModDesc: Provides a /remove command, this is mostly an alternative to /kick, except makes users appear to have parted the channel */
30 * This module supports the use of the +q and +a usermodes, but should work without them too.
31 * Usage of the command is restricted to +hoaq, and you cannot remove a user with a "higher" level than yourself.
32 * eg: +h can remove +hv and users with no modes. +a can remove +aohv and users with no modes.
