[tex4ht] Three questions about errors when using mk4ht to create MathJax compatible files

[Michal Hoftich]

Hello,
I just realized that error message

    /usr/bin/t4ht: fork: retry: No child processes

could mean that `t4ht` application cannot be started. `t4ht` is used
to generate css files and running external commands, like image
conversion, maybe this is the source of your problems, not `NoFonts`
option. You can try to run

    t4ht filename.dvi

yourself, to see whether the css file is generated.

Reagards,
Michal
