COMPLETELY REDONE:
Okay the old version was one hell of a headache, so I made this a LOT better.
Basically what I did this time was make it download the .grd file and theme resources from the SVN, and the application that Chrome uses to build the .rc file. Then it organizes the images in a new folder and pieces the .rc together from what Grit generates.
It's pretty simplistic, and still uses an association bat for organizing (structured differently, though). It's pretty much all automated.

You will need SVN and Python installed.

This will not work in a unicode directory.

Here are the links. :]
Program: xxx
Assoc: xxx
These need to be in the same directory.

And here's the current .rc if you need it: xxx

EDIT: Some of the folders in assoc may not be correct, I was being kinda lazy and just did a regex replacement on the list I had. So if a theme developer is looking through the resulting file structure and sees something wrong, please post, I'll update assoc.bat.

EDIT 2: I've temporarily deleted the links as I realize that there are actually two grds I need to compile. Although I've update it to do that, I seem to be missing something about Grit that's preventing me from finishing it. Gonna ask on the google group and hopefully fix and upload this tomorrow.

I suspect Waha is a robot.
Good job !

Thanks alot Waha! It'll be very useful to me and theme devellopers instead of waiting for other people to do it for us.

It might still take a little technical work if assoc.bat needs to be adjusted.
But really all you'll have to do is, when you find a file that's incorrectly named, search for the filename in assoc.bat, and change it accordingly. Make sure it still looks something like:
SET f10000=path\to\file.png
SET fIDR_BACK=path\
Just don't touch anything left of the equals sign (including it) and don't put any spaces after it and you should be okay.

Just ran it on the new version (3.0.189.0) and there doesn't seem to be any changes or additions since the last one.

If you are using Vista, Command Prompt does not support drag and drop. This feature was removed only for that OS to ''reduce the command window's dealings with the dragged data object''. (You can read more here)

You can download and install a free program called Send to toys that adds a 'Command Prompt' under the 'Send to' menu when you right-click a file, which does basically the same thing as dragging and dropping.

If you are using 2000, XP, or 7, then you shouldn't have any problem dragging and dropping.

Alright all, completely revamped. This should be significantly more easy to use and user friendly.

@Waha

how do you create the .rc file ? and the new image files for the .rc ?

Just run newrc.bat after you've installed everything.
