Since I got frustrated with linux man pages a lot, I am glad to see OpenBSD does it different. (one of the reasons why I finally want to give it a try)

The tar example is indeed much cleaner.

But it seems to be a bit old ...

"A tar archive is often stored on a magnetic tape, but can be stored equally well on a floppy, CD-ROM, or in a regular disk file"

Not that it hurts much, though.
