[comment #4 comment #4:]

gropdf, what more would this add?

> You have not mentioned why you want to suppress CreationDate nor what are
the other related comments.

Thanks, Deri.  I did file this in a hurry.  My main concern was grohtml.

I skimmed the grops(1) and gropdf(1) pages but didn't see what I was looking
for.

I can't seem to get grops's -b option to suppress these kinds of comments. 


$ for N in $(seq 0 31); do echo | groff -Tps -P-b$N | grep -q '%Creat' || echo
%N works to suppress the comments; done


In gropdf(1), I see options to _add more_ comments (-d, -s), but not to remove
any.


$ echo | groff -Tpdf -P-d | grep -E '/(Creator|ModDate|Producer)'
/Creator (groff version 1.22.4)
/ModDate (D:20210523141122+00'00')
/Producer (gropdf version 1.22.4)


Can you offer me some clues?
