As already mentioned, they are the man pages.  By default, they are
gzip(1)'d into /usr/share/man/manX/ to save space.  They are converted
into formatted text using groff(1).  As an example, you can get a
PostScript version of the dd(1) man page with either of the following:
	groff -man /usr/src/bin/dd/dd.1 > dd.ps
	gzcat /usr/share/man/man1/dd.1.gz | groff -man > dd.ps
