% \begin{abstract}
%    The \Lpack{oands} bundle provides a set of 
% miscellaneous characters for use when transliterating ancient scripts.
% This is one in a series for archaic scripts.
% \end{abstract}
% \tableofcontents
%
% \section{Introduction}
%
%    The \Lpack{oands} bundle provides a Postscript Type1 version of an 
% original Metafont~\cite{METAFONT} design 
% of the \thisfont{} fonts. These are odd characters used in transliterating
% archaic scripts, like Hieroglyphic, into a modern alphabet. The font is
% part of a project to provide fonts showing the development of the
% modern Latin alphabet from ancient times.
%
% 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 and package may be in later sections.
%
%
% \subsection{The \thisfont{} script}
%
%    The \thisfont{} font currently consists of just two characters. One is
% a `mirrored apostrophe' accessed via the single left quote character.
% The other is a sign representing a glottal stop; it looks like the numeral 3
% with a flat top and is accessed via the lowercase z character.
%
% \section{The \Lpack{oands} package} \label{sec:usc}
%
%     The \thisfont{} font family is called |oands|. The font is supplied 
% both upright and italic forms and in both
% OT1 and T1 encodings.
%
%
% \DescribeMacro{\oandsfamily}
%    The |\oandsfamily| 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{\textoands}
%    The command |\textoands{|\meta{text}|}| will typeset \meta{text} using the
% \thisfont{} fonts.
%
% The complete font may be printed by |\textoands{` z}|.

% \section{The Metafont code} \label{sec:mf}
%
%
% \subsection{The parameter file}
%
%    We deal with the parameter files first, and start by announcing
% what they are for. The \thisfont{} font comes in one size as a normal
% and italic font.
% 
%    \begin{macrocode}
%<*base10|base10i>
%<base10>%%% OANDSU10.MF  oands upright font at 10 point design size.
%<base10i>%%% OANDSI10.MF  oands italic font at 10 point design size.
%
%    \end{macrocode}
%    The parameters from CMR are used~\cite{CM}. We also
% make sure that \Lpack{cmbase} is loaded as well 
% as plain Metafont.
%    \begin{macrocode}
if unknown cmbase: input cmbase fi

%    \end{macrocode}
%
% \begin{routine}{mirror_comma}
%    We need an additional routine for a `mirrored' comma. It might
% just as well go here as the number of families is very limited and it
% will save on a file. The code is based on Knuth's \file{cmbase.mf}.
%    \begin{macrocode}
def mirror_comma(suffix $, @)(expr dot_size, jut, depth) =
  pickup fine.nib;
  pos$(dot_size,90);
  if square_dots:
    pos$'(dot_size,0);
    z$'=z$;
    dot($',$);                         % squarish dot
    comma_join_ := max(fine.breadth, floor .7dot_size);
    comma_bot_ := max(fine.breadth, floor .5dot_size);
    pos@0(comma_join_, 0); pos@1(comma_join_, 0); pos@2(comma_bot_, 0);
    y@0=y$; y@1=y$1; y@2=y@1-depth;
    x@0r=x@1r=x$'r;
    rt x@2r=good.x(x$-eps);
    filldraw stroke z@0e--z@1e..z@2e;  % tail
  else:
    pos@1(vair,-90); pos@2(vair,0); pos@3(vair,45);
    z@1r=z$r; lft x@2l=hround(x$-.5dot_size-jut)-2eps; x@3=x$+.5u;
    y@2=1/3[y@1,y@3]; bot y@3r=vround(y$-.5dot_size-depth);
    y_ := ypart((z@1{left}...z@2{down}...z@3)
          intersectiontimes (z$r{left}..{right}z$l));
    if y_ < 0: y_ :=1; fi
    filldraw z$l{right}..subpath (0,y_) of (z$r{left}..{right}z$l)--cycle; % dot
    filldraw stroke z@1e{left}...z@2e{down}...z@3e; % tail
