This is package for direct generating html code with tex4ht and lualatex,
without need to process the dvi file with tex4ht command.
Normally, when compiling LaTeX file with htlatex or similar script from the
tex4ht bundle, tex4ht.sty file is included by the script.
tex4ht.sty and commands defined in .4ht files insert \special{t4ht...}
instructions to the output file. This output file is then processes with
tex4ht command, html files are generated at this stage. As last step, t4ht
is called, which is used to generate css file and to run various conversion
commands, like dvi to png for math.
This package aims at removing need to use tex4ht command. Main reason for this
is that tex4ht doesn't support fonts without tfm table, which means that
opentype and truetype fonts used by fontspec package cannot be used.
At this moment, this is just a proof of concept, don't expect perfect results.
tex4ht support adding css information about used fonts, so font shape, weight,
size and other information is preserved. lua4ht doesn't support this at the
moment, only html tags requested by \HCode or \Tag commands are used.

As you can see, diacritics are preserved, but no styling of characters is
provided, as příliš \textit{žluťoučký} is converted to příliš žluťoučký.
pre_output_filter callback is used to traverse TeX nodes. whatsit nodes
produced by \special commands are parsed in order to get html codes,
names of output files, etc. At this moments, only few features are supported,
for list of all possible specials see section backend specials.
