1. Got Zotero? Good.
2. Install MozLab.
3. Restart Firefox.
4. Start MozRepl.
5. Open a terminal.
6. telnet localhost 4242
7. Get the Zotero object:

   var zotero = Components.classes["@zotero.org/Zotero;1"] .getService(Components.interfaces.nsISupports)
   .wrappedJSObject;

   ...but all on one line, no spaces before the dots. Sorry, my formatting plugin went b0nkr5.

8. Surprise your friends, amuse your enemies, bore the big-Zotero-collectionists:

   repl> for each (item in zotero.Items.getAll()) {
   ....> alert(item.getField("title"));
   ....> }

Pretty nifty, eh?
