Assuming you mean:

>Distribution Folder
>	Splash
>	Main.rev


The one thing one cannot do is include any stack/subStack that is 
modifiable in Splash  Otherwise, one is free to bundle or 
unbundle component stacks as it best fits one's (often conflicting) 
goals of simplicity in the eyes of the user vs modularity when

>Distribution Folder

This gets especially complicated in Mac OS 10, because what the user sees as


Transcript sees as

	Folder Splash
		Folder "Contents"
			Folder MacOS
				[Folder you told the DB to put other stacks in]
			[other stuff]

My approach to dealing with this is twofold:

1.  All paths are resolved relative to the effective fileName of the 
stack looking for the file or folder...or to specific 
specialFolderPaths on certain platforms.  This allows the user to 
nest the application folder to any depth desired without the 
standalone losing its files.

2.  Because I am writing [some of] my software for use by other 
developers, I have handlers that will search multiple locations when 
looking for a stack or file.  This allows the developer to choose the 
bundling approach that she/he finds best for the application, AND it 
provides a method of dealing with the application bundle issue while 
scripting cross-platform handlers.
