Sorry, no. When I said "gs >>does<< work" (if that's what your
inference's based on), I meant that ps2pdf works doing the
eponymous ps-->pdf conversion. The input ps file itself is
generated by a compiled C program running as a cgi on the web.

I don't really care about js, per se, just behavior similar to
that of https://viewerjs.org/  What I care about is the html page
that I have to write, where <iframe src="path/somefile.ps"></iframe>
is trivial to write. So a viewerjs-like tool for ps would be great.
I don't care at all (besides curiosity) about its internals; only that
it lets me write an <iframe> inside of which a ps file is displayed.

Thanks, but no thanks:) Not looking to get involved in yet another
project. Just looking for something that already exists.
This is a tool as far as I'm concerned, just like a C compiler
is a tool, but that doesn't mean I want to get involved writing
either one.
