-% \section{Introduction}
-%
-%    The \Lpack{tgothic} and \Lpack{alltgoth} packages provide a Metafont~\cite{METAFONT} version
-% of the \thisfont{} manuscript book-hand that was in use between about the
-% thirteenth and fifteenth centuries~\AD. It is part of a project to provide fonts
-% covering the major manuscript hands between the first century~\AD{} and
-% the invention of printing. The principal resources used in this project
-% are listed in the Bibliography.
-%
-% 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}.
-% The \Lpack{docmfp} package is used for documenting the Metafont portions
-% of the distribution~\cite{DOCMFP}.
-%
-%    Section~\ref{sec:usc} describes the usage of the package.
-% Commented code for the fonts is in Sections~\ref{sec:mf} and~\ref{sec:fd}
-% and source code for the package is in Section~\ref{sec:code}.
-%
-% \subsection{Manuscript book-hands}
-%
-% Before the invention of printing all books were written by hand. The book-hands
-% used by the scribes and copyists for the manuscripts changed as time 
-% went on. Table~\ref{tab:1} lists some of the common book-hands which were used
-% between the 1st and 15th centuries. The later book-hands formed the basis of the
-% fonts used by the early printers, which in turn form the basis of the printing
-% fonts in use today.
-%
-%    The manuscript book-hands were written with a broad nibbed reed or quill
-% pen. Among the distinguishing characteristics of a hand, apart from the 
-% actual shape of the letters, are the angle of the pen (which controls the
-% variation between thick and thin strokes) and the height of a letter compared
-% to the width of the nib. The lower the ratio of the letter height to nib
-% width, the more condensed is the script. The scripts also varied in their
-% typical height. 
-%
-%    Table~\ref{tab:1} gives an `average' x-height for each
-% script, which I obtained by measuring a sample of photographs of
-% manuscripts written in the various hands. About a dozen examples
-% of each book-hand were measured. This figure should not be taken too
-% seriously.
-% 
-%    There was not a sharp division between the use of one hand and another.
-% Many manuscripts exhibit a variety of hands in the same document. For example,
-% the scribe writing in an Uncial hand may have used Roman Rustic letters
-% for capitals. Usually the same pen was used for the two different scripts.
-%
-%    Generally speaking, as a hand got older it became more embelished, and 
-% therefore took longer to write. As this happened a new hand would appear that
-% was faster, and which would eventually make the earlier one obsolete.
-%
-%    Many of the book-hands were single-cased; that is, they did not have an
-% upper- and lower-case as we do nowadays in Western scripts. On the other
-% hand, a script might be majuscule or minuscule. A \textit{majuscule} script
-% is one, like our upper-case, where the letters are drawn between two lines
-% and are of a uniform height with no ascenders or descenders. 
-% A \textit{minuscule} script, like our lower-case, is drawn between four lines 
-% and has ascenders and  descenders.
-%

-%    During the period under consideration arabic numerals were effectively
-% not used. At the beginning they were unknown and even though some knew
-% of them towards the end, the glyphs used for them are not recognisable ---
-% to me they look somewhat like cryllic letters --- and each locality
-% and time had its own highly individualistic rendering. The general rule
-% when using one of these book-hands is to write all numbers using
-% roman numerals.
-%
-%    The Roman alphabet consisted of 23 capital letters --- the J, U and W 
-% were absent. The book-hands initially used both a `u' and a `v' interchangeably
-% but by the 10th century the practice had become to use the `v' before a vowel 
-% and the `u' otherwise. The letter corresponding to the W sound appeared 
-% in England around the 7th century in
-% the form of the runic \textit{wen} character and by about the 11th century
-% the `w' chacter was generally used. The `J' is the newest letter of all, not
-% appearing until about the mid 16th century.
-%
-%    In the first century punctuation was virtually unknown, and typically
-% would not even be any additional space between individual words, never
-% mind denoting ends of sentences. Sometimes a dot at mid-height would be
-% used as a word seperator, or to mark off the end of a paragraph. Effectively
-% a text was a continuous stream of letters. By the time that printing was
-% invented, though, all of our modern punctuation marks were being used.
-%
-%    Among all these manuscript hands, the Carolingian minuscule is the
-% most important as our modern fonts are based on its letter shapes, and it is
-% also at this point in time where the division occured between the black letter
-% scripts as used even today in Germany, and the lighter fonts used elesewhere.
-% The Rotunda and Humanist minuscule hands were developed in Italy and were
-% essentially a rediscovery of the Carolingian minusucle. Guthenberg took the
-% Gothic scripts as the model for his types. Later printers, 
-% such as Nicholas Jenson of Venice,
-% took the Humanist scripts as their models.
-%
-%
-% \subsection{The \thisfont{} script}
-%
-%    With the Gothic hands, used from the thirteenth century, the attention of
-% the scribes moved from the individual letter to the word. The scripts
-% changed to accomodate this interest so the appearance of the letters
-% became subordinate to the overall appearance of the words they formed.
-% Many of the letters appear to be indistinguishable today but the contemporary
-% reading public seemed to have no difficulty.
-%
-%    It was during the heyday of the Gothic scripts that separate capital
-% letters were introduced. Also, as a small concession to legibility,
-% the lowecase `i' acquired a small mark above it. Ligatures were similar
-% to those in Early Gothic. The letter `w' was added to the hand early on
-% and `j' started to appear after 1400, providing the full 26 letter alphabet
-% for the first time.
-%
-%    This font includes both lowercase and (fancy) uppercase letters. Guthenberg
-% used this script as a model.
-%
-% \section{The \Lpack{tgothic} and \Lpack{alltgoth} packages} \label{sec:usc}
-%
-%     The \thisfont{} font family is called |tgoth|. The font is supplied in both
-% OT1 and T1 encodings.
-%
-% \subsection{The \Lpack{tgothic} package}
-%
-%    This is intended for the occasions when some short pieces of text have
-% to be written in \thisfont{} while the majority of the document is in another
-% font. The normal baselineskips are used.
-%
-% \DescribeMacro{\tgothfamily}
-%    The |\tgothfamily| declaration starts typesetting with the \thisfont{} fonts.
-% Use of the \thisfont{} font will continue until either there is another |\...family|
-% declaration or the current group (e.g., environment) is closed.
-%
-% \DescribeMacro{\texttgoth}
-%    The command |\texttgoth{|\meta{text}|}| will typeset \meta{text} using the
-% \thisfont{} fonts.
-%
-% \subsection{The \Lpack{alltgoth} package}
-%
-%
-%    This package is for when the entire document will be typeset with the
-% \thisfont{} font. The baselineskips are set to those appropriate to the
-% book-hand. 
-%
-%    This is a minimalist package. Apart from declaring \thisfont{} to be the
-% default font and setting the baselineskips appropriately, it makes no other
-% alterations. 
-% Vertical spacing
-% before and after section titles and before and after lists, etc., will be
-% too small as the \LaTeX{} design assumes a font comparable in size to
-% normal printing fonts, and the book-hand is much taller.
-% To capture more of the flavour of the time, all numbers
-% should be written using roman numerals. 
-% The \Lpack{romannum} package~\cite{ROMANNUM}
-% can be used so that \LaTeX{} will typeset the numbers that it generates,
-% like sectioning or caption numbers, using roman numerals instead of arabic 
-% digits. 
-%
-% \DescribeMacro{\cmrfamily}
-% \DescribeMacro{\textcmr}
-% \DescribeMacro{\cmssfamily}
-% \DescribeMacro{\textcmss}
-% \DescribeMacro{\cmttfamily}
-% \DescribeMacro{\textcmtt}
-%    The |...family| declarations start typesetting with the Computer Modern Roman
-% (|\cmrfamily|), the Computer Modern Sans (|\cmssfamily|), and the Computer
-% Modern Typewriter (|\cmttfamily|) font families. The |\textcm..{|\meta{text}|}|
-% commands will typeset \meta{text} in the corresponding Computer Modern font.
-%
-%    The \Lpack{alltgoth} package automatically loads the \Lpack{tgothic} package,
-% so its font commands are available if necessary.

-% \section{The Metafont code} \label{sec:mf}
-%
-%
-%    As previously noted, this work is part of a larger project to provide
-% fonts covering the main manuscript book-hands. As such, one of the
-% aims is to produce a coordinated set of fonts, especially as multiple
-% hands might be used in a single document. 
-%
-%    Noting that the hands tend to be somewhat larger than the typical 10pt
-% size (where the x-height is approximately 1.5mm) used for modern books, 
-% I have also designed the fonts
-% at a larger than normal size, then applied some non-linear factors when reducing
-% them down to a 10pt size.
-%    Further, I have used the height of the Carolingian minuscule as a 
-% normalising factor when deciding on the absolute height of any particular
-% script. The x-height of the Carolingian font is made equal to the
-% x-height of the Computer Modern Roman (CMR) font.
-%
-%    Modern fonts are effectively drawn. That is, the outline of the letter is
-% drawn carefully and the center is filled with ink. This is shown to good
-% effect in the Metafont code for the Computer Modern fonts~\cite{CM}.
-% In contrast, the manuscript letters were inked by single pen strokes in
-% a calligraphic manner. I have tried to repeat this calligraphic style
-% in the Metafont code.
-%
-%    As much as possible I have tried to use parameter values from the
-% Computer Modern Roman (CMR) fonts in order to reduce possible
-% infelicities if the CM and manuscript fonts are used together. However,
-% few of the CMR parameters are applicable to the calligraphic style.
-%
-%
-% \subsection{The parameter file}
-%
-%    We deal with the parameter files first, and start by announcing
-% what they are for. The \thisfont{} font comes in three sizes and also as a normal
-% and a bold font.
-%    \begin{macrocode}
-%<*base7|base10|base17|base7b|base10b|base17b>

-%<base10>%%% TGOTH10.MF  Gothic Textura Quadrata at 10 point design size.
-%<base17>%%% TGOTH17.MF  Gothic Textura Quadrata at 17 point design size.
-%<base7b>%%% TGOTHB7.MF    Gothic Textura Quadrata Bold at 7 point design size.
-%<base10b>%%% TGOTHB10.MF  Gothic Textura Quadrata Bold at 10 point design size.
-%<base17b>%%% TGOTHB17.MF  Gothic Textura Quadrata Bold at 17 point design size.
-%
-%    \end{macrocode}
-%    Parameters from CMR are used as much as possible. We also
-% make sure that \Lpack{cmbase} is loaded as well as plain Metafont.

-% \subsection{The \Lpack{alltgoth} package}
-%
-%    The \Lpack{alltgoth} package is intended for use when the entire document
-% will be typeset in the book-hand. This is a minimal package. Because the
-% book-hand should not contain arabic digits a fuller package would redefine
-% anything numbered in \LaTeX{} to use roman instead of arabic numbering.
-% Also, because of the large |\baselineskip| many other aspects of \LaTeX{}
-% to do with vertical positioning should also be redefined. 
-%
-%
-%    Announce the name and version of the package, which requires
-% \LaTeXe{}. It also uses the \Lpack{tgothic} package.

-% The `leading' in the book-hands is a function of the |x-height|, which is 
-% normally much
-% greater than for the CMR fonts. I have borrowed code from Frank Jensen's
-% \Lpack{beton} package~\cite{BETON} to do this. The |x-height| (in points) 
-% for the CMR
-% fonts is given in Table~\ref{tab:cmrx}. Note that the CMR design sizes are
-% 5--10, 12, and 17.28 points. The other values given are scaled from these 
-% figures.
