I tinkered with it a little bit just now, and I notice it does not include the level you list. It may be I cannot understand the command line, as the little summery is hard to make sense of.

when I use it I type the following:

Packpacker /z ex01 ex02

this gets it going (It throws a hissy fit if I put just ex01), but it ignores ex01 and packs ex02 along with everything else in the series.

In hindsight, It may work right If I input ex01 twice.

Other than that, it works beautifully, and I like the convenience it provides.
