Where can I find the 'elf' thingy?

A noob question again
: Where can I find that 'elf' program that allows you to track the python files? I've read through a lot of threads, and I'm sure I've missed it somewhere so I place this question here. As you may guess I have this trouble with my Journals - can't get them to open up in age although the books have hotspots on them. I have tried for several days now and I can't get any further. My .pak imports the GUI.py, Defs.py and Journals.py allright so I can't see the mistakes anywhere.
I've used D'Lanors Journals template and I've looked at other .py and .pak files, deleted and done it over again several times. Now I think I must track something with that 'elf' I read about. Other suggestions are of course welcome!!
