Re: using pic with -Thtml

[hbezemer]

Thanks Dave, that makes it clear for me.

I've tried my first minimal example. but now with -ms and this gives a good 
result. 
Thus: echo ".PS\nbox\n.PE" | pic | groff -Thtml -ms works.

Would it be useful to modify the -mm PS and PE macros so that they work with 
grohtml
since the macro package is provided with groff by default?
