[l2h] processing packages without perl styles

[Alberto Buffolino]

Hi all,
I have a big problem whith latex2html conversion.
I have a .tex document which uses a not-usual package, asd2.sty, 
provided with document and located in the same directory. When I try to 
convert the document, the HTML output has alt tag with commands and text 
unrecognized by latex2html and so converted in images (I have also 
failed conversion of images during process).
So, how can I tell latex2html to use this style, or pass it to latex to 
process commands and environment there defined?
Thanks very much in advance...
Alberto
