Keep in mind, just requiring it only loads and (demi)compiles the code.
You'll need to call one of the subroutines in order to start execution. Which
is why you may want to consider loading the text of the required file into a
scalar and eval'ing it, instead. That'll cause normal execution of the code
body, should you need to work it that way.
