Ah, perfect then. This is precisely the kind of information I was after.

I did at one point, but that was back when my desktops were primarily 
Linux. I was interested in lower-level code than that at the time and 
so I was looking at MUSCLE and then found SOSSE too. It's nice to see 
things have been progressing elsewhere.

Ah! pkgsrc-wip. I knew there was a reason I began syncing up with the 
wip tree. Thank you for the pointer, it's most helpful. Of course 
interesting things would have to be sitting there right under my 
nose. :)

Thanks again,
