Yes... For example here's how I added my own "<package>" type targets:

The built in target types <dll>, <lib>, <exe>, <template>, etc. are 
supported similarly. Just look for "gTARGET_TYPE_ID(_) = _ ;" in 
boost-base.jam and other *.jam files.

I can explain the above code if that's needed, but it's fairly simple ;-)
