%     This package provides new commands and environments for setting 
%     ragged text which are easy to configure to allow hyphenation.
%     An earlier attempt to do this was the style
%     \package{raggedright}\cite{raggedri} by the same author.

%  \section{The problem}
%  ^^A
%  \LaTeX{} has three commands (\cs{centering}, \cs{raggedleft}, and 
%  \cs{raggedright}) and three environments (\env{center},
%  \env{flushleft}, and \env{flushright}) to typeset ragged text.
%  The environments are based upon the commands (\env{center} uses
%  \cs{centering}, \env{flushleft} \cs{raggedright}, and 
%  \env{flushright} \cs{raggedleft}).
%
%  These commands have, however, one serious flaw: they render
%  hyphenation almost impossible, and thus the text looks \emph{too}
%  ragged, as the following example shows:
%  \setcounter{unbalance}{2}
%  \begin{multicols}{2}
%     \small\fussy

%   ``The \LaTeX{} document preparation system is a special version
%     of Donald Knuth's \TeX{} program.

%     high-quality typesetting, especially for mathematical text.''

%
% ^^A -----------------------------
%
%  \section{Old ``solutions''}
%
% ^^A -----------------------------
%
%  \subsection{\LaTeX}
%  ^^A
%  \LaTeX{} defines e.\,g.\ \cs{raggedright} as follows:
%    \begin{macrocode}
%<*latex>
\def\raggedright{%
   \let\\=\@centercr
   \@rightskip\@flushglue
   \rightskip\@rightskip
   \leftskip\z@
   \parindent\z@}
%    \end{macrocode}
%  Initially, \cs{@flushglue} is defined as
%    \begin{macrocode}
\@flushglue = 0pt plus 1fil
%</latex>
%    \end{macrocode}
%
%  Thus the \cs{rightskip} is set to |0pt plus 1fil|.
%  Knuth, however warns \cite[p\@. 101]{KnuthTeXa}:
%  \begin{Quote}
%   ``For example, a person can set \cs{rightskip=0pt plus 1fil},
%     and every line will be filled with space to the right.
%     But this isn't a particularly good way to make ragged-right
%     margins, because the infinte stretchability will assign zero
%     badness to lines that are very short.
%     To do a decent job of ragged-right setting, the trick is to set
%     \cs{rightskip} so that it will stretch enough to make line breaks
%     possible, yet not too much, because short lines should be
%     considered bad.
%     Furthermore the spaces between words should be fixed so that
%     they do not stretch or shrink.''
%  \end{Quote}
%
% ^^A -----------------------------
%
%  \subsection{\plain{}}
%  ^^A
%  \plain{} \TeX{} defines an special version of
%  \cs{raggedright}, which operates the way Knuth describes it;
%  but which can not be used whith \LaTeX, because \LaTeX{} redefines
%  \cs{raggedright}.
%    \begin{macrocode}
%<*plain>
\def\raggedright{%
   \rightskip\z@ plus2em
   \spaceskip.3333em
   \xspaceskip.5em\relax}
%    \end{macrocode}
%
%  \plain{} provides also a version of \cs{raggedright} for typewriter
%  fonts
%    \begin{macrocode}
\def\ttraggedright{%
   \tt
   \rightskip\z@ plus2em\relax}
%</plain>
%    \end{macrocode}
%
%  \end{multicols}
%  \setlength{\parskip}{^^A
%     .3\baselineskip plus.05\baselineskip minus.05\baselineskip}
%
% ^^A -----------------------------
%
%  \section{Our solution}
%
%  Since the \plain{} solution can not be used with \LaTeX, we have to
%  redefine it and make it possible to configure it for personal
%  preferences.
%
% ^^A -----------------------------
%
%  \subsection{The macros}
%  ^^A
%  \DescribeMacro{\Centering}
%  \DescribeMacro{\RaggedLeft}
%  \DescribeMacro{\RaggedRight}
%  \cs{Centering}, \cs{RaggedLeft}, and \cs{RaggedRight} can be used in 
%  the same way as \cs{centering}, \cs{raggedleft}, and 
%  \cs{raggedright}:
%  Just type the command, and after that the whole text will be set
%  centered, ragged-left or ragged-right.
%
%  For example, we switched on \cs{RaggedRight} on the top of this
%  text, and consequently this text was set
%  ragged-right.\footnote{^^A
%    Actually we also set \cs{RaggedRightRightskip} higher than usual
%    (|0pt plus 4em|) because of all the long command names which
%    make linebreaking difficult.}
%
%  \DescribeMacro{\justifying}
%  \NEWfeature{2003/01/04}%
%  \cs{justifying} switches back to justified text after ragged text
%  has been switched on.
%  \changes{v2.00}{2003/01/04}{New command \cs{justifying}}
%
%  The new commands \cs{Centering}, \cs{RaggedLeft}, and
%  \cs{RaggedRight} are fully compatible with their counterparts in
%  \LaTeX, but implement the \plain{} solution and can be easily
%  configured using the following parameters:

%  ^^A
%  This package requires the following package:
%  \begin{description}
%     \item[\normalfont\package{everysel}\cite{everysel}]
%        It is used to distinguish between monospaced and proportional
%        fonts.
%     \item[\normalfont\package{footmisc}\cite{footmisc}]
%        It is used by the \option{footnotes} option; at least
%        version~5.00 (2002/08/28) is needed.

%  ^^A
%  A first version of this package for \LaTeX2.09 was named
%  \package{raggedri}\cite{raggedri}.
%  Laurent Siebenmann (\url{lcs@topo.math.u-psud.fr}) with his
%  style \package{ragged.sty}\cite{ragged} provided the final impulse
%  for this new implementation.\newline
%  The code for \cs{justifying}, \env{justify} and the overloading of
%  \cs{@arrayparboxrestore} is incorporated from the
%  \package{raggedr}\cite{raggedr} package by James Kilfinger
%  (\url{mapdn@csv.warwick.ac.uk}).\newline
%  Without the constant nagging of Rainer Sieger
%  (\url{rsieger@awi-bremerhaven.de}) this package might not
%  be.\newline
%  Markus Kohm (\url{markus.kohm@gmx.de}) provided the code for
%  \cs{@gnewline}.\newline 
%  Frank Mittelbach (\url{frank.mittelbach@latex-project.org})
%  provided the impetus for version~2.00.\newline
%  Rolf Niepraschk (\url{Rolf.Niepraschk@ptb.de}) and Hubert G\"a\ss{}lein
%  found many bugs and provided fixes for them and code for new
%  features.

%  \subsection{Distinguishing between monospaced and proportional fonts}
%  ^^A
%  To set ragged text with proportional fonts \emph{and} monospaced 
%  fonts correctly, we must distinguish between these two kinds of
%  fonts \emph{everytime} a font is loaded.
%  Otherwise the settings for e.\,g.\ a proportional fonts would be
%  in effect if you start \cs{RaggedRight} in \cs{rmfamily} and
%  then switch to \cs{ttfamily}.
%
%  The goal is to have a rigid interword space in all fonts.
%  \TeX's interword space is |\fontdimen2 plus \fontdimen3 minus \fontdimen4|.
%  This can be overwritten by setting \cs{spaceskip} (space between
%  words, if nonzero) and \cs{xspaceskip} (space at the end of
%  sentences, if nonzero).
%
%  We do the setting with the help of \package{everysel}\cite{everysel},
%  which allows us to define code which is (hopefully) executed after
%  every fontchange in a \LaTeX{} document.\footnote{^^A
%     It \emph{is} executed after every \cs{selectfont}, so if you stay 
%     within NFSS and don't declare your fonts with commands like 
%     \cs{newfont} and then switch to them, it will work.}
