Importing from DesignWorkshop (.dw)

Does anyone know of a script for importing meshes from the Artifice DesignWorkshop (.dw) format? These files appear to be plain ASCII, so it shouldn’t be too hard to write an import script for it.

I’ve never used DesignWorkshop before, but I notice that Artifice provide an online tree generator, DesignWorkshop Tree Machine, which looks simple and powerful, but only outputs files in DesignWorkshop format. I’d love to use some of those trees in blender.

Thanks,
Keith.
