Yes, I already implemented this, and it works very well. However, I 
think it's too little. I guess I'm not really certain how the installer 
should actually work, which is one of the reasons I'm fishing for an answer.

It think anything less than a page where the user has to answer this 
manually will be too subtle for the data dir. I'm happy with this on 
stuff like installing header files for installation.

The reason I'm worried is if a user had a previous installation with the 
datafiles in there, and installs in the same directory, it might be easy 
to overwrite the files.

I think a separate page with three options to choose from

- install new files
- use existing files in the installation directory
- use data files in a separate location

Or something like this. If someone already did something this advanced 
with CPack, it would be great to hear about it. I suspect that I'll have 
to work directly in the nsis module file to implement this.

Anyway, components doesn't answer the uninstall problem.
