How to build new html help on mac?

[Mojca M. <moj...@gm...>]

Dear list,

I don't have enough insight into development internals, this is why I
would like to ask how I could build the new HTML help on mac. (In the
long run Mac could also use HTML help instead of inline help in
terminal, depending on user configuration. But for that one would need
one-page-per-help-request as opposed to a single huge HTML file, so
that I could say "help term postscript" and get just the HTML page
describing postscript terminal.)

But to start with I would like to know how I can build the new html
help in the first place. I somehow see that there is
    -../src/$(TARGET) -e "winhelp=1" $(D)plotstyles.gnu
in makefile for windows, but I cannot call that makefile from osx. There is also
    docs/plotstyles.gnu:if (winhelp==1) out = "./windows/"
but I'm not sure if name "windows" is in the place. HTML files are
much more generic than just for windows. As I said, there is a great
chance that Mac OS X could use them as well (if some skilled mac
developer steps forward and tells how to proceed).

I would only like to ask for instructions for building the help
(ideally being available out-of-the-box as a target in Makefile), and
maybe to rename "windows" to something more generic/html-ish. The
final file is only for windows of course, but the HTML files are more
generic.
