I’m going to start compiling a library of useful functions (such as the ones [here](http://www.kirupa.com/forum/showthread.php?t=249149)). If I compile many of them into an external class, import it, but only use a few per project, do the other functions get loaded regardless?

Basically I want to have a bunch of useful functions at my disposal but I dont want the unused ones to be published with the swf, increasing the file size/load time. How should I approach it?
