This is -current/amd64. My /etc/man.conf in its entirety is 'output paper a4'. The A4 paper size is what we mostly use around these parts; otherwise I would not even have a man.conf of course.
I am not sure whether man -Tpdf and man -Tps honour the paper size. man -Tpdf sox > man.pdf man -Tps sox > man.ps Viewing the PDF file in gv(1), it says "y841x595" in the size box. Viewing the PS file, it says "Default" in the size box. I don't know the PDF or PS syntax so I can't tell from the files themselves, but other PDF and PS files that I know have A4 pages show as "A4" in gv(1). I can always override it with tools; but occassionaly a printer will choke on a file with "unknown" page size. Jan
