Everybody: Do *not* click on the following links,
http://download.tuxfamily.org/eigen/Cxx98.pdf
http://download.tuxfamily.org/eigen/Cxx03.pdf
as that *might* trigger an unauthorized download of copyrighted
material, which would obviously have the effect of putting the ISO out
of business and halting all further development of the C++ language
specification.
Thanks for your attention,
