Enabling announce

[cyphur]

i want to know how to enable announcing using a sitebot w/ this script...i don't understand exactly what im supposed to do

* On default, announcing is disabled everywhere, use zip/sfv paths to enable annouces and private paths to disable
* NOCHECK DIRS AND ANYOTHER DIRS ARE IGNORED.
* GROUP DIRS HAVE NO PUBLIC ANNOUNCE, NO SYMLINKS AND ARE EXCLUDED FROM MP3 BANS
