Set-theoretical mathematics in Coq

Comes with a tar archive containing updated versions of the Coq proof files which were previously attached to math.HO/0311260We give a brief discussion of some of the issues which have arisen in the course of formalizing some classical set-theoretical mathematics in the Coq system. This sprouts from, expands and replaces a chapter of math.HO/0311260 which will be removed in revision, and also contains as a tar-attachment to the source file the revised and expanded version of the proof development which had been attached to math.HO/0311260
