Latest version of diagxy

I have just uploaded to CTAN the latest version of diagxy. It is also available from my own web site: http://www.math.mcgill.ca/barr/papers/. The main thing it does is work well with the beamer macro \uncover (and relatives) to allow you use the node and arrow mode to add arrows (or for that matter, nodes) as overlays on diagrams. It also solves a problem that one user reported to me that the registration on repeatedly laying down the same ink was not perfect and he claimed that his nodes were thickened. I never observed this but the same fix apparently fixes it. Also, I have added \hyperref to the diaxydoc file. Michael [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
