contents of pigsmoke

Hi pig !

I've been looking at the contents of pigsmoke.jar, and I dont see much:

TestPigTest.class
TestGruntParser.class

And a few text files.

1) Aren't the pigsmoke jar artifacts meant to include a broad range of pig
induced mapreduce jobs?

2) looking in the build.xml, its a little tricky to tell exactly how
"pigsmoke" is constructed... im a little rusty on ant/ivy. So maybe can
someone point me to some clues on how to investigate how pigsmoke is
constructed?

Maybe im missing something....
