I tested the patch on linux and I found some quirks. The least important is that when exporting to html, the export dir is filled with byproduct files such as .dvi, .aux, .log, .idv, and others which have nothing to do with the export itself. The most important is that dvipng cannot find graphics files, which are therefore left blank. I think that this is due to the fact that they are not in the directory which is the current one when htlatex is called. Notice that both problems above are avoided when using the wrapper for htlatex that I posted previously. So, my proposal is to convert that script in python, place it in the lib/scripts directory and use it as the converter on all platforms when htlatex is detected. As regards symlinks, they only work with cygwin, not in a native environment. Windows shortcuts are something different and are not really symlinks. However, I heard that symlinks are supported in Vista. > I'll implement this when I get a chance, probably tonight. Should be > pretty painless.
