Version 2: * it doesn't generate PNG if it already exists * it supports more TeX * TeX used as a shell argument is escaped properly now ISSUE 18: Escaping from further passes is very important. Following things must me protected from interpretation: * TeX markup if uses choses "leave it as TeX" mode * contents of alt= tags * Messages saping that some TeX couldn't be generated. Should I just generate unique character strings like <nowiki> does ? ISSUE 19: I'm not sure if \mbox is right thing to have. Isn't it meant to do things other than math ? I'm no TeX expert so please comment. ISSUE 20: How ugly HTML will we allow ? Sums and integrals in HTML will be redable but extremely ugly. Well, we could implement more sophisticated HTML rendering algorithms, for example using a table for that. But I'm not sure if it's worth the effort. ISSUE 21: I'm using: http://www.fi.uib.no/Fysisk/Teori/KURS/WRK/TeX/symALL.html http://pl.wikipedia.org/wiki/Encje_HTML to get list of things we should support. Is there some better list ?
