+% \section{Introduction}
+%
+% The \Lpack{inslrmin} and \Lpack{allimin} packages provide a Metafont~\cite{METAFONT} version
+% of the \thisfont{} manuscript book-hand that was in use from the
+% sixth century~\AD{} onwards. 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}
+%
+% The \thisfont{} hand has been in use from the sixth century.
+% It was originally developed in Ireland by St.~Patrick's monks
+% as a less formal and faster hand than the Insular majuscule,
+% the most famous example of which is the \textit{Book of Kells}.
+%
+% Although the letter shapes in this book-hand are principally of
+% a lower-case form, there are a few that are shaped like capital letters.
+% For example, the `n' appeared as both an `n' and as an `N',
+% while the `f' and `r' were written like `F' and `R'.
+% Some letters had multiple forms. As well as the `n' the `r' could be written
+% as either `r' or `R'.
+%
+% The letters were written very close together and the scibes used many
+% adhoc ligatures. A favourite was using a long `e' before a letter
+% with a bar at the x-height, and joining the crossbar of the `e' to
+% the bar of the following letter, for instance the pair `eg'.
+% I have only provided the ampersand, `\&', as a ligature, standing for
+% `et' which is the Latin for `and'.
+% Letters were also stretched if a line
+% needed some filling. For example, the capital form of the `N' might be
+% stretched to 2 or 3 times its normal width.
+%
+% Usually the
+% lettering in a manuscript was all one size. If the scribe felt the need
+% for `capital' letters then, using the same pen, would either write a larger
+% \thisfont{} letter or a letter from one of the more formal book-hands.
+% I have provided a set of `capital' letters that are only a little larger
+% than the normal letters for use in running text.
+% During the time the \thisfont{} script was used the alphabet only had 24
+% letters. I have included the missing J.
+%
+% Arabic numerals were unknown at this time, so all numbers were written
+% using the roman numbering system. I have provided \thisfont{} versions of
+% the arabic digits.
+%
+% Punctuation was used, but not with the frequency of today.
+% A sentence might be ended with
+% a dot at mid-height or a paragraph ended with a colon, also at mid-height.
+% The comma was was a small
+% slash; the semi-colon was known, as was the single quotation
+% mark which was represented by a raised comma.
+%
+%
+% \section{The \Lpack{inslrmin} and \Lpack{allimin} packages} \label{sec:usc}
+%
+% The \thisfont{} font family is called |imin|. The font is supplied in both
+% OT1 and T1 encodings.
+%
+% \subsection{The \Lpack{inslrmin} 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{\iminfamily}
+% The |\iminfamily| 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{\textimin}
+% The command |\textimin{|\meta{text}|}| will typeset \meta{text} using the
+% \thisfont{} fonts.
+%
+% \subsection{The \Lpack{allimin} 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{allimin} package automatically loads the \Lpack{inslrmin} 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.

+%<base17>%%% IMIN17.MF Insular Minuscule at 17 point design size.
+%<base7b>%%% IMINB7.MF Insular Minuscule Bold at 7 point design size.

+%<base17b>%%% IMINB17.MF Insular Minuscule Bold at 17 point design size.

+% \subsection{The \Lpack{allimin} package}
+%
+% The \Lpack{allimin} 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{inslrmin} 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.
