25 /* $ModDesc: Provides support for the /SILENCE command */
27 /* Improved drop-in replacement for the /SILENCE command
28 * syntax: /SILENCE [+|-]<mask> <p|c|i|n|t|a|x> as in <privatemessage|channelmessage|invites|privatenotice|channelnotice|all|exclude>
30 * example that blocks all except private messages
34 * example that blocks all invites except from channel services
36 * /SILENCE +chanserv!services@chatters.net ix
38 * example that blocks some bad dude from private, notice and inviting you
39 * /SILENCE +*!kiddie@lamerz.net pin
41 * TODO: possibly have add and remove check for existing host and only modify flags according to
42 * what's been changed instead of having to remove first, then add if you want to change
