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