Require() vs Include()

Hi, A tiny question: why to use require() when include() works just as well and even better when there are some conditions like if{} ? I ask it because although I read many articles on this issue I found no reason for myself to use require() instead of include() and I have driven some huge projects in PHP. Why do I see these hardcore PHP gurus writing PHPLIB, mySQLadmin and examples in their articles using require() where include() would fit just as perfect? WHERE THE TRIIIICK? It escapes from me ...
