No thank you!  PULEEAZE!!!!!

What the heck is the purpose of a *REFERENCE* manual supposed to be
anyway?  I want *exact* documentation about a given implementation.
Anything more or less is most definitely not OK.  If I want to look at
other implementations manual pages I can do that.  If I want to look at
a "standard" then I can do that.  I don't need a half-baked non-standard
manual page that doesn't describe the implementation hosting it!

Certainly historical information is OK, but only so long as it is
explicitly documented as historical and no longer supported.

Information about future migration paths is also OK, but again only so
long as it is explicitly noted as such.

Information about standards conformance, or lack thereof, is equally
welcome, but only if it does not obscure the description of the actual

I do not need another overly genericised "how to program on Unix" book!
