Not quite mark.
It comes with each version of Blender and it's all in the python scripts folder (and subfolders BPyModules/colladImEx)
I've tinkered with it myself. I suspect its getting updated through the blender builds, for example people patching it through these channels, but correct me if I'm wrong because I'll need to know where to submit my own mods:
[
projects.blender.org]
and submit matching email according to:
[
www.blender.org]
I've tinkered with the object nesting, triangle translation, and put a wrapper for googleEarth KML, and today I'm tackling library-group references which should go in the library_nodes section of .dae I suspect.
I learned python with the O'Reilly book Learning Python.
Good luck.
I'll see you on one of the blender communities.
