I gave a try with Hevea to compile PBE book in HTML It gave many errors, I try to fix a few but there are many. It will require rewriting a lot of the PBE macros with ifelse{latex}{html} directives. This is what I did for the drgeo doc (http://documentation.ofset.org/drgeo2/fr). Does someone try with latex2html? Hilaire -- Education 0.2 -- http://blog.ofset.org/hilaire
