% \begin{abstract}
% \noindent As an alternative to the \LaTeX\ standard environments
% \quoa/ and \quoe/, the \quo/ package provides a consolidated
% environment for displayed text. First-line indentation is activated by
% adding a blank line before the \quo/ environment. A key--value
% interface allows to configure font properties and spacing and to
% control orphans within and after the environment.
% \end{abstract}
%
% \section{Introduction}
%
% The \LaTeX\ standard classes as well as many custom classes provide
% two environments for displayed text: \quoa/ and \quoe/. They can be
% described as follows: \blockcquote[p.~480]{Kop04}{\textins{In} the
% \quoa/ environment \textelp{} text is indented on both sides relative
% to the normal page margins. Paragraphs within the environment are
% marked with an additional indentation of the first line.
%
% \textins{The \quoe/ environment is} \textins*{t}he same as the \quoa/
% environment except that the first line of a paragraph is not indented;
% instead, additional line spacing comes between paragraphs.}
%
% So when to prefer one environment to the other? A common suggestion is
% to use the \quoa/ environment for quotes extending to several
% paragraphs so that the paragraph indentation matches that of the
% surrounding text \cite{Kot11,Lam94,Oet11}. For single-paragraph quotes
% one may either use \quoe/ or, in case the quoted text starts a new
% paragraph (which should be indicated by indentation), \quoa/.
%
% Why didn't Leslie Lamport, the initial developer of \LaTeX, implement
% a single environment for displayed text and provide control over its
% first-line indentation by other means, e.g. the presence of a blank
% line (or a |\par| command) before the environment? The likely reason
% is that Lamport envisaged an additional application of the \quoe/
% environment, namely \blockcquote[p.~24]{Lam94}{a sequence of short
% quotations, separated by blank lines}. But such a sequence (which
% seems to be of limited use) could also be put into effect by stringing
% together several instances of a consolidated quoting environment.
%
% Some unfavourable effects of \quoa/ and \quoe/ in their present form
% are:
%
% \begin{itemize}
%
% \item The \quoa/ environment isn't suited for documents which use
% vertical spacing instead of indentation to denote the start of new
% paragraphs. If one retroactively adopts such a layout, one should
% change the definition of  |\quotation| and |\endquotation| to |\quote|
% resp. |\endquote|.
%
% \item The side-by-side existence of two environments for displayed
% text narrows the utility of the \textsf{csquotes} package which
% provides higher-level wrapper environments, e.g. for quoting in a
% foreign language and specifying the source of citations. Currently,
% \textsf{csquotes} uses \quoe/ as a backend environment, but with
% \LaTeX's default settings, this is not appropriate for multi-paragraph
% quotes.
%
% \end{itemize}
%
% \section{Using the \quo/ package}
%
% As an alternative to \quoa/ and \quoe/, the \quo/ package provides a
% consolidated environment for displayed text. Besides being indented
% relative to the normal page margins, the \quo/ environment behaves as
% follows:
%
% \begin{itemize}
%
% \item A blank line before the environment marks a new paragraph,
% i.\,e. the environment's first line will be (additionally) indented in
% this case (assuming a positive |\parindent|). The mechanism also works
% for adjoining \quo/ environments of the same depth and for nested
% quotes.\footnote{See \cite[p.~120--121]{Fis95} for an example of
% nested quotes.}
%
% \item If a \quo/ environment directly follows a sectioning command
% (which may or may not be considered good style), its first line won't
% be indented.\footnote{That is, unless the |@afterindent| switch was
% set to true, e.g. by loading the \textsf{indentfirst} package. In this
% case, the quote's first line will be indented.}
%
% \item As the start of a new paragraph is already indicated by
% first-line indentation, the vertical space before and after the \quo/
% environment is kept constant (contrary to list environments like
% \textsf{itemize} and \textsf{enumerate}).
%
% \item Because the \quo/ environment uses a custom mechanism to control
% orphans\footnote{If a page break occurs after the first line of a
% paragraph, that line is referred to as \enquote{orphan}.} within and
% after it, it is not affected by \LaTeX\ bug 4065 (|\clubpenalty| not
% always being reset after list environments).
%
% \end{itemize}
%
% The options provided by \quo/ use the key--value interface
% `\meta{key}=\meta{value}'. Set them globally with
% |\usepackage[|\meta{options}|]{quoting}| or for single environments
% with |\begin{quoting}[|\meta{options}|]|. For boolean options, the
% default value is \textsf{false}, and specifying \meta{key} is
% equivalent to \meta{key}\textsf{=true}.
%
% \begin{description}[font=\sffamily]
%
% \changes{v0.1a}{2011/09/08}{New option \textsf{indentfirst}}
%
% \item[indentfirst]\SpecialOptIndex{indentfirst} An option that allows
% to override \quo/'s indentation mechanism and to manually switch
% on/off first-line indentation. The permitted values are \textsf{auto},
% \textsf{true}, and \textsf{false}. The default value is
% \textsf{auto}.\footnote{The \textsf{indentfirst} option may act as a
% fallback solution for cases where \quo/'s indentation mechanism fails.
% Currently, first lines will always be indented a)~immediately after
% \texttt{\textbackslash begin\{document\}} b)~after a
% \textsf{sloppypar}, \textsf{center}, \textsf{flushleft}, or
% \textsf{flushright} environment. Thanks to Enrico Gregorio for
% pointing out \quo/'s behaviour with respect to \textsf{sloppypar},
% \textsf{center} \& friends.}
%
% \changes{v0.1b}{2012/02/21}{Improved syntax of options \textsf{font}
% and \textsf{font+}}
%
% \item[font]\SpecialOptIndex{font} The font used for typesetting the
% contents of a \quo/ environment. Permitted values are the names
% (without preceding backslash) of \LaTeX's font-switching/formatting
% commands; e.\,g, use \textsf{font=itshape} to typeset quotes in
% italics. (By default, \quo/ uses the font/formatting of the
% surrounding text.) To specify several font properties, use a
% comma-separated list of font/formatting names, e.g.,
% \textsf{font=\{itshape,raggedright\}} (note the surrounding
% braces).\footnote{Before \quo/ v0.1b, \textsf{font+} had to be invoked
% for specifying several font properties.}
%
% \item[font+]\SpecialOptIndex{font+} Font properties used for
% typesetting the contents of a \quo/ environment in addition to those
% properties specified by \textsf{font} (and previous calls of
% \textsf{font+}).
%
% \changes{v0.1b}{2012/02/21}{New options \textsf{begintext}
% and \textsf{endtext}}
%
% \item[begintext]\SpecialOptIndex{begintext} Additional text (e.g., an
% opening quotation mark) to be typeset at the start of a \quo/
% environment. By default, no text is added.
%
% \item[endtext]\SpecialOptIndex{endtext} Additional text (e.g., a
% closing quotation mark) to be typeset at the end of a \quo/
% environment. By default, no text is added.
%
% \item[leftmargin]\SpecialOptIndex{leftmargin} The width of the
% environment's left-hand indentation relative to the surrounding text.
% The default value is |\leftmargin|.\footnote{Note that the value of
% \texttt{\textbackslash leftmargin} depends on the depth of the \quo/
% environment, i.\,e. nested quotes will feature smaller indentation by
% default.}
%
% \item[rightmargin]\SpecialOptIndex{rightmargin} The width of the
% environment's right-hand indentation relative to the surrounding text.
% By default, \textsf{rightmargin} matches \textsf{leftmargin}.
%
% \item[vskip]\SpecialOptIndex{vskip} The vertical space before and
% after a \quo/ environment. The default value is the sum of |\topsep|
% and |\partopsep|.
%
% \item[listvskip]\SpecialOptIndex{listvskip} A boolean option that, if
% enabled, adjusts \quo/'s vertical spacing to that of list environments
% (and ignores \textsf{vskip} in the process).
%
% \item[noorphanfirst]\SpecialOptIndex{noorphanfirst} A boolean option
% that controls whether orphans are prohibited in the first paragraph of
% a \quo/ environment.
%
% \item[noorphanafter]\SpecialOptIndex{noorphanafter} A boolean option
% that controls whether orphans are prohibited directly after a \quo/
% environment.
%
% \item[noorphans]\SpecialOptIndex{noorphans} A shortcut boolean option
% enabling both \textsf{noorphanfirst} and \textsf{noorphanafter}.
%
% \end{description}
%
% \DescribeMacro{\quotingsetup}
% The command |\quotingsetup|, which takes a comma-separated list of
% key--value options as argument, allows to change the attributes of the
% \quo/ environment mid-document.
%
% \DescribeMacro{\quotingfont}
% The options \textsf{font} and \textsf{font+} do not accept values
% which itself take an argument. In such cases you must resort to
% redefining the command |\quotingfont|, e.g. by including
% |\renewcommand*{\quotingfont}{\setstretch{1.5}}| in your document
% preamble (with the \textsf{setspace} package loaded).

%
% At the end of \quo/, we typeset the replacement text of
% \textsf{endtext}. (We also remove any preceding space if we are in
% horizontal mode; this does not apply if, e.g., the \quo/ environment
% closes with a list environment like \textsf{itemize} or
% \textsf{enumerate} plus a blank line.) After that, the following
% actions are taken:
% \begin{itemize}
%
% \item The \LaTeX\ kernel switch |@endpe| is set to false (so that
% |\@doendpe| won't be executed);
%
% \item The state of the |quo@noorphanafter| switch is forwarded outside
% the current group (using \TeX\ syntax);
%
% \item |quo@afterquo| is globally set to true;
%
% \item |\quo@doendquo| is executed after the current group.
