% \section{Introduction}
%
% Within the \NFSS{} distribution there is a \LaTeX{} file
% \texttt{nfssfont.tex} which can be used to test new fonts, produce
% font tables showing all characters, etc. This is an addaption of a
% program originally written by Don Knuth. When you run this file
% through \LaTeX{} you will be asked to enter the name of the font to
% test. Your answer should be the external font name without any
% extension, e.g.\ \texttt{cmr10} (Computer Modern Roman 10pt) or
% \texttt{yinit} (Yannis Haralambous' Initial font). You are then
% requested to enter a command. Probably the most important one is
% |\table|, which will produce a font chart.  To switch to a new test
% font, type |\init|; to finish the test, type |\bye|; and to learn
% about all the other possible tests type |\help|.
%
% Interfaces and code will probably change  in the future. This is at
% the moment only a crude addaption of the test program for the
% Computer Modern fonts.

% \section{The code}
%
% A testbed for font evaluation (see The METAFONTbook, Appendix H)
% changed for \LaTeX{} with \NFSS.
%
% This program should get a complete rewrite some day. Any volunteer?

On November 14, 1885, Senator \& Mrs.~Leland Stanford called together
at their San Francisco mansion the 24~prominent men who had been
chosen as the first trustees of The Leland Stanford Junior University.
They handed to the board the Founding Grant of the University, which
they had executed three days before. This document---with various
amendments, legislative acts, and court decrees---remains as the
University's charter.  In bold, sweeping language it stipulates that
the objectives of the University are ``to qualify students for
personal success and direct usefulness in life; and to promote the
publick welfare by exercising an influence in behalf of humanity and
civilization, teaching the blessings of liberty regulated by law, and
inculcating love and reverence for the great principles of government
as derived from the inalienable rights of man to life, liberty, and
the pursuit of happiness.'' \moretext
