% \begin{abstract}
%    The \Lpack{trajan} package provides a set of uppercase fonts as 
% carved on the Trajan column in Rome in 114 \textsc{ad}.
% \end{abstract}

%
% \section{Introduction}
%
% Around the beginning of the 16th century several authors published designs
% for uppercase characters. The more well known among these were Albrecht
% D\"{u}rer who wrote \textit{On the Just Shaping of Letters} which was
% published in Nuremberg in 1525, and Geofroy
% Tory who wrote \textit{Champ Fleury} which was published in Paris in 1529.
% Fra Luca Bartolomeo de Pacioli preceeded by of these by developing his
% recipe for uppercase characters in 1497 and which was published in
% \textit{De Divina Proportione} at Venice in 1509. Metafont versions
% of the D\"{u}rer and Pacioli fonts are available\footnote{In directories
% \texttt{duerer} and \texttt{pacioli} respectively, in the font area.}
% from CTAN.
%
%    Many typographers rank the capitals carved on the Trajan column in
% Rome, dated at 114~\textsc{ad}, as the high point of the Roman's
% artistic legacy. These letter shapes were the best basic form in the
% subsequent development of uppercase fonts. The top line of the letters
% on the Trajan column are about six feet above eye level, with the letters
% being about four and a half inches tall. There are six lines of text
% and the letter height on the lowest line has been reduced to about 75\%
% of the those at the top of the inscription.
% 
% Fortunately, Jan Tschichold~\cite{TSCHICHOLD92} provides
% a more accessible source for the Trajan characters, and I have used
% his work in developing this rendition of the lettering.
% 
% 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{GOOSSENS94}.
%
%    Section~\ref{sec:usc} describes the usage of the package.
% Commented code for the fonts and source code for the package is in 
% later sections.
%
%
% \section{The \Lpack{trajan} package} \label{sec:usc}
%
%    The Romans did not have the J, U or W letters in their abecedary, and
% rarely used H, K or Z. Jan Tschichold designed glyphs for these six
% letters to complement the character set on the Trajan column.
%
%   I have also added modified versions of Knuth's Computer Modern punctuation
% characters so that, perhaps, the Trajan font could be used as a 
% titling font.
%
% Trajan's font as provided here consists of the uppercase letters, 
% the punctuation marks  !.,;:`'?,
% the hyphen together with the en- and em-dash,
% and the analphabetic characters ()[]\&.
% All the chacters are accessed by typing them as you usually do in \LaTeX.
%
% \DescribeEnv{trjnfamily}
% The family name is \texttt{trjn}. Use the \texttt{trjnfamily} environment
% for long stretches of text.
%
% \DescribeMacro{\texttrjn}
% Use \verb?\texttrjn{a word or two}? to typeset a \texttt{word or two} in
% the Trajan font.
