None that I'm aware of. Unfortunately, this sort of brain damage seems 
to be par for the course for this particular product. I think they 
thought that just because they "can" produce a file like this, that it 
then became a good idea. I think they are just dumping out a 
database-like structure to a file-based structure.

You had some interest in Plan 9, right? Do they support it?

I'm a bit biased: I do mostly Groovy on Grails for the day job, and I 
think Groovy is great. :)

And yes, it has a good zip library. The idiom for using zip in Groovy is 
rather Java-esque, though - unless you want to use metaobject 
programming to change the behavior and sort of "add" it to the language:

I think if you are already using Java a lot - adding Groovy to the mix 
is an easy sell to suits and can gain the tech people a lot of win, IMHO.

If you weren't already in that ecosystem - maybe not as interesting.
