%
% \section{Introduction}
%
%    The \Lpack{fonttable} package lets you typeset a font's character set
% in tabular and/or running text forms.
%
% This manual is typeset according to the conventions of the
% \LaTeX{} \textsc{docstrip} utility which enables the automatic
% extraction of the \LaTeX{} macro source files~\cite{COMPANION}.
%
% \section{The package}
%
%    The package provides commands to typeset a table of all the glyphs in
% a given font and to typeset an example of regular text. For font designers
% it provides commands to typeset a `test' glyph among sets of glyphs
% from the font.
%
% \DescribeMacro{\fnthours}
% As a convenience, \cs{fnthours} prints the time of day when the file was 
% processed; it uses the 24 hour clock notation. (The macro \cs{today} prints
% the date when the file was processed.)
%
% \subsection{Table and texts}
%
%
% \DescribeMacro{\fonttable}
% The command \\
% \cs{fonttable}\marg{testfont} \\
% typesets a table showing all the
% glyphs in the \meta{testfont}, where \meta{testfont} is the name of a 
% font file\footnote{More precisely, the name of a \texttt{.tfm} file.}
% like \texttt{cmr10} (for Computer Modern Roman) or \texttt{pzdr} 
% (for Zapf Dingbats).
%
% NOTE: The \Lpack{mftinc} package~\cite{MFTINC} for pretty-printing 
% METAFONT code also defines a \cs{fonttable} macro that is akin to this 
% one. If you want to use both packages together then you can use the following
% general procedure for when a macro \cs{macro} is defined in both 
% \Lpack{packA} and \Lpack{packB} packages.
% \begin{verbatim}
% \usepackage{packA}
% \let\macroA\macro%   save packA's definition
% \let\macro\relax%    undefine \macro
% \usepackage{packB}%  now it's packB's definition of \macro
% ...
% \macro %   use the packB defintion
% \macroA %  use the packA definition   
% \end{verbatim}
%
% \DescribeMacro{\xfonttable}
% The command \\
% \cs{xfonttable}\marg{encoding}\marg{family}\marg{series}\marg{shape} \\
% typesets a table showing all the
% glyphs in the font with encoding \meta{encoding} (e.g., T1 or OMS),
% family \meta{family} (e.g., \texttt{ppl} for Palatino or \texttt{cmbrs}
% for CM Bright Math (OMS)), font series \meta{series} (e.g., \texttt{sb}
% for semibold of \texttt{m} for medium), and font shape \meta{shape}
% (e.g., \texttt{n} for normal or \texttt{sc} for small caps).
% For example: \\
% \verb?\xfonttable{U}{pzd}{m}{n}? \\
% for Zapf Dingbats.
%
% \DescribeMacro{\pikfont}
% The command\footnote{The name was chosen in an attempt to avoid
% clashes with other macros that might perform similar functions.}   \\
% \cs{pikfont}\marg{encoding}\marg{family}\marg{series}\marg{shape} \\
% selects the font with encoding \meta{encoding} (e.g., T1 or OMS),
% family \meta{family} (e.g., \texttt{ppl} for Palatino or \texttt{cmbrs}
% for CM Bright Math (OMS)), font series \meta{series} (e.g., \texttt{sb}
% for semibold of \texttt{m} for medium), and font shape \meta{shape}
% (e.g., \texttt{n} for normal or \texttt{sc} for small caps).
% For example: \\
% \verb?\pikfont{T1}{ppl}{m}{sc}? \\
% for Palatino small caps.
% The size of the font corresponds to the current setting (e.g.,
% \cs{footnotesize}, \cs{normalsize}, \cs{Large}). It can also be
% changed after being selected by the incantation \\
% \cs{fontsize}\marg{size}\marg{baselineskip}\cs{selectfont} \\
% where \meta{size} is the normal height and \meta{baselineskip} is the
% distance between text lines; the measurement system is \texttt{pts}
% but just use numbers with no units specified. For example: \\
% \verb?\fontsize{12}{15}\selectfont? \\
% for a 12pt font with 15pts between baselines.
%
% If you are unsure about the meaning of the various arguments 
% of \cs{xfonttable} and \cs{pikfont} see
% \textit{The Companion}~\cite[Chapter 7]{COMPANION} or the 
% \textit{LaTeX2e font selection} manual (\texttt{fntguide.tex}; try
% \verb?texdoc fntguide?).
%
% \DescribeMacro{\fontrange}
% The package attempts to populate the table with a maximum of 256 glyphs,
% numbered from 0 to 255.
% The \cs{fontrange}\marg{low}\marg{high} declaration changes this by reducing
% the range so that it extends from \meta{low} to \meta{high}, where \meta{low}
% should be at least 0 and \meta{high} at most 256, and \meta{low} less than
% \meta{high}.
%
%    The table is composed of blocks of sixteen characters. If necessary the
% value of \meta{low} is adjusted lower and \meta{high} is adjusted higher
% to match this block structure. For example, if you wanted a table of the
% lower 128 characters then \verb?\fontrange{0}{127}? would do the job,
% while the upper half of a 256 character font could be tabulated via
% \verb?\fontrange{128}{255}?.
%
% \DescribeMacro{\decimals}
% \DescribeMacro{\nodecimals}
% Normally each cell in the table includes the decimal number of the position
% in the (256) character set. \cs{nodecimals} turns off this numbering and
% \cs{decimals} turns it on. The default is \cs{decimals}.
%
% \DescribeMacro{\hexoct}
% \DescribeMacro{\nohexoct}
% Normally the columns and rows in the table are numbered using hexadecimal 
% and octal numbers. These can be turned off by \cs{nohexoct} and turned 
% on again with \cs{hexoct}, which is the default.
%
% \DescribeMacro{\ftablewidth}
% The font table's width is the length \cs{ftablewidth}, which by default
% is set to the normal textwidth (or more exactly, to \cs{hsize}). The table
% itself is left aligned. However, if \cs{nohexoct} is in effect the width of
% the table is its natural width.
%
% \DescribeMacro{\fntcolwidth}
% When \cs{nohexoct} is in effect the minimum width of a table column
% is \cs{fntcolwidth}. This is initially declared as \\
% \verb?\setwidth{\fntcolwidth}{0.08\ftablewidth}?
%
% \DescribeMacro{\fonttext}
% The command \cs{fonttext}\marg{testfont} typesets an example text using
% the \meta{testfont} (e.g. \texttt{cmr10}).
%
% \DescribeMacro{\simpletext}
% \DescribeMacro{\fulltext}
% The example text can be just a paragraph and a line of capitals,
%  or include more complex accented
% words as well. Following the declaration \cs{fulltext} the complex words are
% included as well as the example paragraph. The default is \cs{simpletext}
% for just the paragraph.
%
% \DescribeMacro{\regulartext}
% The command \cs{regulartext}\marg{fontspec} typesets the example text
% using \meta{fontspec}, for example \verb?\rmfamily\itshape?
% or \verb?\pikfont{T1}{pnc}{m}{it}?.
%
% \DescribeMacro{\fonttexts}
% \DescribeMacro{\regulartexts}
% The macro \cs{fonttexts}\marg{testfont}\marg{text} typesets \meta{text} using
% the \meta{testfont} (e.g., \texttt{cmr10}). Similarly the macro
% \cs{regulartexts}\marg{fontspec}\marg{text} typesets \meta{text}
% using \meta{fontspec} (e.g., \verb?\rmfamily\itshape? or 
% \verb?\pikfont{T1}{ppl}{m}{it}?).
%
% \DescribeMacro{\germanparatext}
% \DescribeMacro{\latinparatext}
% \cs{germanparatext} expands to a German language paragraph, borrowed from the 
% \Lpack{blindtext} package~\cite{BLINDTEXT}. 
% \cs{latinparatext} expands to one version of
% a paragraph of the traditional \textit{lorem ipsum} dummy Latin text.
% Either, or both, of these could be used as the \meta{text} argument
% to \cs{fonttexts} or \cs{regulartexts}. \\
% NOTE: These were originally called \cs{germantext} and \cs{latintext}
%  but on 2009/05/14 I was told that the \Lpack{babel} package defines \cs{latintext}, 
%  which causes unexpected results if it is used in the same document as this
%  package. To try and be on the safe side I renamed \cs{germantext}
% as well as \cs{latintext}.
%
% \DescribeMacro{\aztext}
% \DescribeMacro{\AZtext}
% \DescribeMacro{\digitstext}
% \DescribeMacro{\punctext}
% \cs{aztext} expands to the lowercase Latin alphabet a to z, and \cs{AZtext}
% is the corresponding command for the uppercase A to Z. 
% The macros \cs{digitstext} and \cs{punctext} expand respectively to the
% digits 0 to 9, and to the typical punctuation marks. In all cases there 
% is a space between each character. 
%
% \subsection{Testing a glyph}
%
%    The macros here are a reimplementation of Donald Knuth's 
% \texttt{testfont.tex}, which is available from CTAN. 
%
%    In the following, the value of a glyph argument can be specified as
% its location in the font (i.e., as a decimal number). With a few exceptions,
% if the glyph is within the visible ASCII range (33--126) it may instead be 
% specified by the ASCII character prefixed with a single open quote 
% mark\footnote{Sometimes called a
% `backquote'.} (`). The exceptions are nos: 37 (\verb?%?), 92 (\verb?\?)
% 123 (\verb?{?) and 125 (\verb?}?) (but there may be others). 
% In any case, the glyph representing the
% character \texttt{p} can be specified either as \texttt{`p} or as 
% \texttt{112}. 
%
%    The glyphs are taken from the current font. If the font does not
% have Latin alphabet glyphs in the ASCII locations then 
% in the descriptions below phrases like `lowercase alphabet' or `uppercase
% alphabet' or `digits', should be taken to mean (the glyphs in) those 
% locations.
%
% \DescribeMacro{\glyphmixture}
% \cs{glyphmixture}\marg{T}\marg{S}\marg{E} typesets the \meta{T} (test) glyph 
% between the glyphs in the range from \meta{S} (start) to \meta{E} (end).
% For example \\
% \verb?\glyphmixture{`e}{`f}{`g}? will produce \\
% \texttt{efeeffeeefffef} \\
% \texttt{egeeggeeegggeg}
%
% \DescribeMacro{\glyphalternation}
% \cs{glyphalternation}\marg{T}\marg{S}\marg{E} typesets the \meta{T} 
% glyph alternately between each glyph in the range from \meta{S} 
% to \meta{E}.
% For example \\
% \verb?\glyphalternation{`e}{`f}{`g}? will produce \\
% \texttt{efefefefefefefefe} \\
% \texttt{egegegegegegegege}
%
% \DescribeMacro{\glyphseries}
% \cs{glyphseries}\marg{T}\marg{S}\marg{E} typesets the \meta{T}
% glyph between the glyphs in the range from \meta{S}
% to \meta{E}.
% For example \\
% \verb?\glyphseries{`e}{`f}{`h}? will produce \\
% \texttt{efegehe}
%
% \DescribeMacro{\glyphalphabet}
% \DescribeMacro{\GLYPHALPHABET}
% \cs{glyphalphabet}\marg{T} typesets the \meta{T} glyph between
% each letter of the lowercase Latin alphabet plus a few others. 
% \cs{GLYPHALPHABET}\marg{T}
% does the same but using the uppercase Latin alphabet.
% For example, the output of \\
% \verb?\glyphalphabet}{`3}? is like \\
% \texttt{3a3b3c3d3e3f3g\ldots3z3\char31 3}\verb?~?\texttt{3\char33 3\char34 3}
%
% \DescribeMacro{\glyphlowers}
% \DescribeMacro{\glyphlowers}
% \DescribeMacro{\glyphdigits}
% \cs{glyphlowers} takes each character of the lowercase alphabet in turn as
% a test glyph and sets it interspersed among the other lowercase characters.
% \cs{glyphuppers} and \cs{glyphdigits} are similar except that they use
% the uppercase alphabet and the ten digits instead. For example, 
% \cs{glyphdigits} produces output like \\
% \texttt{000102030405060708090} \\
% \texttt{101112131415161718191} \\
% \texttt{202122232425262728292} \\
% \ldots \\
% \texttt{909192939495969798999}
%
% \DescribeMacro{\glyphpunct}
% \cs{glyphpunct} sets a collection of words with an assortment of
% punctuation marks.

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
