KDE menu - where is it kept?

[Timothy Murphy]

I've seen this question asked many times,
but never seen a simple answer:
Where exactly is the list of items in the main F/Start menu kept?

I added Kontact to the menu by right-clicking on the F icon,
and going into Menu Editor,
but I would have thought there was already an entry for Kontact
somewhere on the system?

I suppose another way to ask my question is:
What decides which items are on the menu?
