archive and have a question for this:

Well, i'm just about having the same problem. I use LyX-1.3.4 and
latex2html-2002.2.1_2 here, and want to define URLs in a lyx file to
convert into html.

I find the above translated line in the tex file, but it seems that
latex2html doesn't know about \IfFileExists{} and so doesn't load
the url.sty and therefore the URLs are not generated.

If i export the LyX file into LaTeX and try to convert the LaTeX
file into html, i get the following eror:

Unknown commands: IfFileExists

If i remove the if routine and put a plain \usepackage{url} into it,
the error sounds like this:

No implementation found for style `url'

though the url.sty is present (comes with latex2html in texinputs

Do you have any idea where the problem might be?

With kind regards,
