- * Family 0x0013 - Server-Side/Stored Information.
- *
- * Relatively new facility that allows certain types of information, such as
- * a user's buddy list, permit/deny list, and permit/deny preferences, to be
- * stored on the server, so that they can be accessed from any client.
- *
- * We keep 2 copies of SSI data:
- * 1) An exact copy of what is stored on the AIM servers.
- * 2) A local copy that we make changes to, and then send diffs
- * between this and the exact copy to keep them in sync.
- *
- * All the "aim_ssi_itemlist_bleh" functions near the top just modify the list
- * that is given to them (i.e. they don't send SNACs).
- *
- * The SNAC sending and receiving functions are lower down in the file, and
- * they're simpler. They are in the order of the subtypes they deal with,
- * starting with the request rights function (subtype 0x0002), then parse
- * rights (subtype 0x0003), then--well, you get the idea.
- *
- * This is entirely too complicated.
- * You don't know the half of it.
