Yes. There are 3 modes now: boxon, lineon, dragon, each with a 
corresponding off function. The off functions are just synonyms for boxoff. 
I've committed both the gif/jpeg version, and the png version to CVS so you 
can take a look at them. (And a working example is at 
www2.tetonwyo.org/mapserver)

I exchanged emails with Kari a couple weeks ago about getting jBox onto the 
utilities page instead of mapplet, but she was gone for a while, and then I 
was gone, so we haven't got it together yet. I'll continue to pursue that 
with her unless you would prefer to.

And I still have it on my "to do" list to get a build system together in Ant.

Rich
