If I remove old kde3.3 stuff, how do I preserve the menu items

[David Baron <d_baron@012.net.il>]

If I cannot "canonize" the konstructed 3.5, then another alterantive would be 
to remove most kde3.3 items (using apt-get), leaving the libs and a few items 
to meet dependencies of applications I would want to install or upgrade. This 
would recover a lot of disk space and get this stuff off the apt-get/kpackage 
listings.

I believe I would need to copy all user's menus, do the delete and then, if 
all apps have been removed from the menus, restore them. The 3.5 apps would 
be run from these menu items.

I have not been able to find the menu files (I presume some XML somewhere in 
~/.kde)  Where are they?

Is this plan valid?
