dynamic loading

["Arshavir Grigorian" <suppressed>]

Hi,

I am wondering if anyone has experience with a framework for
dynamically loading certain modules into an application and executing
certain code based on whether a certain module is loaded (available or
not). By "dynamically", I do not mean loading run-time, only being
able to safely exclude certain modules at startup. One place this
could come in handy is when selling an app to 2 clients of whom one
has purchased all the functionality and the other has not, and you
don't want to give them certain module(s). I am guessing one could
accomplish this by using a macro processor (m4) to preprocess Perl
code before it's "released", but it would probably be somewhat
painful.

I'd love to hear what others have done in similar situations. Thanks in advance.
