[Bf-python] What are "Tail" bones?

[Bill Baxter]

I must confess I don't really understand your question, but I found the 
blender2cal3d.py script very helpful.
It includes a function  "blender_bone2matrix(head, tail, roll)" that 
might help you understand how to convert the head-tail-roll into a more 
standard rotation representation.   Here's a link:

or if that doesn't work
