It sounds like you need to spend a little time reading perldoc perlmod. But a couple of quick facts may help you out: In perl, a single file may contain *multiple* packages and/or classes. Similarly, a single package may be spread out over *multiple* files. A package need not have classes in it. In perl, packages and files may be flexibly divided in many ways. I'm by *no* means an expert on packages/modules in perl, so I'll leave the rest to the documentation and the more knowledgeable monks.
