Multiple document types for a standalone

[Paul Dupuis]

So if your application has a single document, you can specify the type/extension and the documents icon in the Standalone settings (for OSX and Win), set up some code in your app to handle (on OSX and Win)
when someone double clicking on your app's icon to launch your app and pass it the clicked on document. All good.

What if your document has multiple document types? Easy enough to handle in code - check the command line parameters in Windows or appleevents under OSX for the different doc type and handle accordingly.

However, how do you package the icons for multiple document types when the standalone settings appear to only allow a single document icon?

I am not super OSX literate, but it appears I could just place additional icns files in the resource folder in the .app bundle and configure the standalone setting to use a customer pList that I edit
manual to add additional document entries under the <key>CFBundleDocumentTypes</key> <array> part of the XML plist. Is this the right approach?

Under Windows, I can use setRegistry() function to add registry entries for additional document types, but how do I get the icons for these packaged into the .exe file? Is there a way?
