Oh, I don't get such huge diff, see the attachment. Hmm.
caused compilation errors on tex4ht-html4.tex Yeah, that's probably what's going on. I'll work on it again when I have a chance. it is: http://www.ctan.org/pkg/tex4ht Oops, I forgot that we moved it to obsolete. but it seems to be really old version with "obsolete" message, but It's the last release Eitan made. We've never managed to make another. Moving to /obsolete is usual for CTAN, though I suppose I could ask them to delete it completely. sometimes people try to install it, I am afraid Really? It never occurred to me that anyone would be crazy enough to get that obviously-ancient tex4ht from CTAN and try to do anything with it. Using Eitan's packages was never the easiest thing to do ... Thanks, K
