At the moment it only deals with line type 126 (which is BSpline).
It can be downloaded here: blender_version_igs_import.py. Warning: only deals with entity type 126.
At the moment the igs importer probably doesn't do much good beyond importing BSplines. But it happens to do a remarkable job at importing .igs files from http://www.dgp.toronto.edu/~shbae/ilovesketch.htm, which is why i wrote it.
