I dont need code for this, just a basic flowchart or something.

I have a registry file (the thing that is made when you export the registry) of all the keys for the settings of my proggy. I want to import that, but only certain parts of it. So say I had these settings:
Code:
Settings
	Old People
	Peanut Butter
	Squirels
and I wanted to import just old people and squirells. Here's my idea so far:

Export current settings (backup)
copy the backup, so there are 2 backups.
Import the entire new settings (including peanutbutter)
export oldpeople
export peanutbutter
delete all registry settings
import one of the backups
import old people
import peanutbutter
delete backup unless there was an error

Does that make sense? or is there a better way to do it?
the file is a bit too complicated to parse BTW.
