Hello, John Collins (http://www.phys.psu.edu/~collins/) kindly added TeX4ht support into latexmk to his list of features to add :)
A promising starting point can be tested by downloading and unzipping the archive: http://gte.univ-littoral.fr/members/dbitouze/pub/latex/divers/tex4ht-support-into/latexmk_ht-tar-gz/downloadFile/file/latexmk_tex4ht.tar.gz and, in the "latexmk_tex4ht" directory, to test htlatex compilations with: ./myhtlatex2 <file> Of course, feedbacks are welcome! -- Denis
