Fair point.

Glibc doesn't contain man-pages.  The man pages were written mainly by
the people who document the linux kernel, that's why it says "Linux
Programmer's Manual".  This is an overhang from the days when Linux
used Libc6 which was maintained by Linux kernel folks.  It's confusing
because they don't maintain that part of the system anymore.

Yep.  It's a fairly common problem, not restricted to manpages either.
