Thanks again. Comments below.

Yes, I will do that.

No, I really do want to convert an artifact to a file, and not the other
way around. For example, I want to copy a third-party jar (artifact)
directly into an ISO image.

Yes, that is one of the frustrations of the buildr documentation. I have
used rake extensively in the past, but it was several years ago. It
would be great to have one document that covers buildr+rake. I know it
would be difficult. Hopefully you can at least continue to add examples
and other documentation to mention the useful parts of rake as they
apply in a buildr context.

With javadocs, at least when you are looking at a class, you get to see
all the methods that were inherited. rubydocs would be much nicer if
they could do that as well.

Ok. So let's say I want to create 'justjars' and 'fullrelease' tasks in
my master project.

Ah, got it. I actually had it before, but was looking in the wrong place
for the output. Something like this, which seems to work:

  task 'justjars' => [project('part1').package(:jar), 

And hopefully this (which I haven't been able to test yet):

  task 'fullrelease' => [project('iso').iso, project('exe').exe]

Assuming I create custom iso and exe tasks in the sub-projects. Does
that sound about right?
