>3. Include a small Greasemonkey emulation layer for the Greasemonkey-specific APIs
(we already have this implemented).

Alas, this is incomplete.  See  Issue 4476 :
>I'm going to mark this closed now, even though we don't fully implement all the 
Greasemonkey APIs. We should open new bugs, for, eg, fully implementing 
GM_xmlhttpRequest, GM_setValue/GM_getValue, etc.

Yes, I'm aware of that. That seems to be orthogonal to this bug, though.

I like it. Does that mean that we'll show GM scrips as extensions in the extensions 
manager? One advantage would be that this would make it easy to manage (remove) them.

I'm going to try and get this in for beta.

Whee!

Aaron's got this out for review.

Got lgtm, was fighting with linux/mac, finally figured out last issue. Landing shortly.

Add first class support for user scripts.

TBR=mpcomplete@chromium.org
BUG=22103
TEST=Install a user script (such as from userscripts.org). You should get the extension install UI and the
script should show up in the extension management UI. It should also work, though some scripts use
Firefox-specific APIs and those won't work in Chromium.

User scripts will not be installed, if "Ask where to save each file before downloading" 
is checked at Options > Under the Hood > Downloads.

In that case, confirmation of install is not displayed on the Download shelf,
and the *.user.js file is just downloaded as a file.
Tested with Developer Build 31081 on WinXP.

Thanks for the report, I have created  issue 26801  for this but. Please star that if 
you'd like to follow the progress.

When a userscript is set to run on a subdomain, it seems to run twice when installed
as an extension.


e.g.
{{{
// ==UserScript==
// @name           GM Chrome Test
// @namespace      Chrome
// @description    GM Chrome Test
// @match        http://docs.jquery.com/*
// @version        0.1
// ==/UserScript==


alert('test');

@thegooddale: This was  bug 29644 , which is fixed on trunk and should go out in the dev 
and beta releases.

Fixing a bulk edit. Looks like the search query was not correct.
