[tex4ht] make output of tex4ht go to sub-folder without leaving temporary and intermediate files in the current folder?

[Nasser M. Abbasi]

Is there a way to tell tex4ht to generate all its output
into a sub-folder from where the latex file is ?

Suppose I have this tree

----------------
   foo.tex
   a.png
-----------------

Where inside foo.tex there is includegraphics to a.png

--- foo.tex ----------
\documentclass{article}%
\usepackage{graphics}
\begin{document}
\includegraphics{a.png}
\end{document}
-------------------------

Now I want to build HTML file from foo.tex but want all
the intermediate and any auxiliary files tex4ht generated
(including any html files) to go to a sub-folder, say A/, so
I'd _LIKE_ to end up with

-----------------------------
   foo.tex
   a.png
     +
     |
     A/---- foo.htm
            foo.xref
            foo.tmp
            etc.....
            a.png
            
--------------------------------

I use the option

    htlatex foo.tex "" "" -dA/

But it still leaves many many files in the same folder, and
it only copies foo.htm and a.png to the sub-folder.

I have to go clean all that each time. I want the parent
folder to remain the same as before.

Is there a way to do that?

thanks
