Оригинально, познавательно и с юмором! Отличная работа!

Everything else is finally simply details -- significant details, but variants on this theme. index.php is the controller, the menu method determins what the "present page" is, and a lot of occasions get fired in the act of building that page. Plugin modules can hook into those events and shift the work flow/furnish additional information/etc. That is also part of the reason a lot of Drupal resources revolve around making modules. Without modules, Drupal does maybe not really DO anything other than say, 'Someone asked to get a page! Does it exist? No? OK, I'll serve up a 404.'
