in reply to Splitting program into modules

Is there a program that reads a Perl source code and prints out the names of all the subs declared in that file?

Perhaps an even more useful program might also show the dependencies, so at a quick glance you could see all the subs and which one depends on which one. If they are called sub a3e {} then, of course, that won't reveal much. But if they are called "calc_offset" or "getTimeZone" or something that is self-explanatory, then such a program would help a lot in breaking down this huge code into comprehensible chunks.

Is there such a program?
