Hello.
I have a patch for ms2html, which adds a new macro to insert hyperlinks
into documents, currently, the best solution we have currently is
hard-coding html tags,
example in htmlroff:
.html a <a href="/link">
this is a link
.html a
or in ms2html:
._H <a href="/link">
this is a link
._H </a>
both of which are not very good. It'd be nice if we had a
common way to insert hyper links into html and pdf (and possibly ps)
documents, without hard-coding any thing specific to those formats.
this is what .LN macro tries to solve, at least for ms2html, for now.
i'll send a patch for htmlroff and mhtml later on.
comments are welcome. :)

Seems OK to me, but you'll want to format this code in accordance to style(6).

hi mkf,
also, as a general rule when working with existing code, you
should get acquainted with the conventions and style as much
as possible before writing anything. basically what the last
paragraph of style(6) DESCRIPTION says.
it's only when writing new programs that you should try to
follow the bullet points as much as possible.

I don’t see much of a reason not to imitate Groff’s UR/UE macros.
