+%     ragged text which are easy to configure to allow hyphenation.
+%     An earlier attempt to do this was the style

+%  ^^A
+%  This package is \emph{unmaintained}. 
+%
+%  I will not actively work on this package anymore. I \emph{may}
+%  merge merge requests to the repository on Gitlab
+%  (\url{https://gitlab.com/hagenbuch/ragged2e}).  If you want to
+%  become the maintainer of this package, contact me and I may hand
+%  over the repository to you. Or fork the package on Gitlab.
+%
+%  I will \emph{not} upload new versions to CTAN.
+%
+%  \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
+%     \raggedright
+%     \cs{raggedright}:\\
+%   ``The \LaTeX{} document preparation system is a special version
+%     of Donald Knuth's \TeX{} program.
+%     \TeX{} is a sophisticated program designed to produce
+%     high-quality typesetting, especially for mathematical text.''
+%     \cite[p\@. xiii]{lamport86}
+%
+%     \newpage
+%     \RaggedRight
+%     \cs{RaggedRight}:\\
+%   ``The \LaTeX{} document preparation system is a special version
+%     of Donald Knuth's \TeX{} program.
+%     \TeX{} is a sophisticated program designed to produce
+%     high-quality typesetting, especially for mathematical text.''
+%     \cite[p\@. xiii]{lamport86}
+%  \end{multicols}
+%
+%  \setcounter{unbalance}{0}
+%
+% ^^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

+%  Laurent Siebenmann (\url{lcs@topo.math.u-psud.fr}) with his

+%  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

+%  Markus Kohm (\url{markus.kohm@gmx.de}) provided the code for

+%  Frank Mittelbach (\url{frank.mittelbach@latex-project.org})
+%  provided the impetus for version~2.00.\newline
+%  Rolf Niepraschk (\url{Rolf.Niepraschk@gmx.de}) and Hubert G\"a\ss{}lein

+%  \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.}
+%
+%  \begin{macro}{\if@raggedtwoe@spaceskip}
+%  \cs{if@raggedtwoe@spaceskip} signals the use of commands defined by
+%  \package{ragged2e} to the command inserted into \cs{selectfont}.
+%  It is set to true by these commands and restored to false by \TeX{} 
+%  when the scope of them ends.
