[Groff] automatic equation numbering

[Anton Shterenlikht]

Hi

My groff experience is very limited.
I've been using latex for years, so
probably I just need to get used to
groff ways of cross-referencing.

I'd like to give a label to every
equation, and then use those labels
for cross-referencing, as in latex.

I've done someting like this with
mm EC + mmroff, but it's very clunky.

So I wanted to ask - what is the easiest
way of achieving equation (or table,
figure, etc. ) cross-referencing with groff?
I've only tried mm and ms, but will try
other macro packages if advised.

Thanks

Anton
