[Wine] Pre-downloaded Wine Gecko Installer?

[notfed]

Hi,

I've been doing a lot of testing in isolated WINEPREFIX environments.  So, I'm constantly creating new .wine folders and having to run winecfg to set them up.  Well, each time I do this, I have to watch the Wine Gecko Installer progress bar, and sometimes it can be slow (like if my internet connection is bogged up).  

I wish I could keep a local copy that WINE would pull instead of downloading it every time.  I've seen someone in this forum post a few commands to use to install Gecko (basically a copy of the installed components, along with a registry key to import), but (A) importing the registry keys didnt work for me and (B) I need a way to do this in a single script without requiring human interaction.

Anyone have any ideas here? Basically, I want to end up with a script "InstallGecko.sh", that installs it to my WINEPREFIX directory, with no popups, no questions asked.
