All this definition does is to append a text-string to the $HTML_META variable.
As such, it will be used verbatim, in the appropriate place.
The &revert_to_raw_tex is to undo any translation of special characters,
such as < " ' > that may have occurred already.

Thus you would have to give the complete string as an argument:

\htmlmeta{<META NAME="keywords" CONTENT="longkeyword, nasslug, first, second">}

You could try using macros within the argument:

\newcommand{\METANAME}[1]{<META NAME="#1" }
\newcommand{\MCONTENT}[1]{CONTENT="#1" }

then use:

\htmlmeta{\METANAME{keywords}\MCONTENT{longkeyword, nasslug, first, second}>}




\namedmeta{keywords}{longkeyword, nasslug, first, second}

No. There is just a single mandatory argument, and no optional one.
The syntax and possible usage of META commands is so broad that I didn't want
to restrict usage by imposing too much structure in the \htmlmeta macro itself.

I didn't do much work on this, as there was no compelling need.
Try the above suggestions and report back with the results.

Hmm. Of the thousands of entries recorded there,
there are  173 for latex tex   and  several for  latex manual .
The  366 for  latex pic  are ambiguous.
The rest mainly have a quite different slant.

Suggestions on how to make use of this with LaTeX2HTML are most welcome.

Hope this helps,
