%
% \begin{documentation}
%
% \pkg{Copyedit} implements copyediting support for \LaTeX{}
% documents. Authors can enjoy the freedom of using, for example,
% using words with \textsc{us} or \textsc{uk} or Canadian or Australian
% spelling in a mixed way, yet, they can choose any one of the usage
% form for their entire document irrespective of kinds of spelling
% they have adopted. In the same fashion, the users can have the
% benefit of following features available in the package:
%
% \begin{enumerate}
% \item Localization --- British-American-Australian-Canadian
% \item Close-up, Hyphenation, and Spaced words
% \item Latin abbreviations
% \item Acronyms and Abbreviations
% \item Itemization, nonlocal lists and labels
% \item Parenthetical and serial commas
% \item Non-local tokenization in language through Abbreviations and
%   pronouns.
% \end{enumerate}
% 
% \section{Package Loading}
% 
% The \pkg{copyedit} package can be loaded with the command:
% \begin{verbatim}
%   \usepackage[&lt;options&gt;]{copyedit}
% \end{verbatim}
%
% \begin{function}{\ceset,\cesetup}
% \begin{syntax}
%   \cs{ceset} \Arg{options}\\
%   \cs{cesetup} \Arg{options}
% \end{syntax}
% There is a user-friendly function, namely, \cs{ceset} or
% \cs{cesetup} available which can be used anywhere in the document
% to change the options or behaviour of the package from that point
% onwards. The usage of the function is:
%
% The \meta{options} shall be provided as a comma separated list.
% \end{function}
%
% \section{Using the Features}
%
% \subsection{Localization --- British, American, Australian and Canadian}
%
%  \begin{function}{\definevariant}
%  The package provides a database of commonly used English language
%  words in all the above four variant spelling. One can add new
%  entries to the list with the command:
%  \begin{syntax}
%    \cs{definevariant}\Arg{uk}\Arg{us}\Arg{au}\Arg{ca}
%  \end{syntax}
%  The variants, \meta{uk}, \meta{us}, \meta{au} and \meta{ca} denote
%  British, American, Australian and Canadian spelling respectively.
% \end{function}
%
% \begin{function}{\vara}
%  \begin{syntax}
%   \cs{vara} \Arg{variant}
%  \end{syntax}
%  In the document, one can use the macro \cs{vara}\marg{variant}.
%  The user is free to use a combination of words of various spelling,
%  but output will totally be dependent on the option of locale chosen
%  for the document.  For the sake of distinction and to prove our
%  point, let us assume that the word \meta{color} has the following
%  four different spelling in four different locale:
% \end{function}
% \begin{enumerate}[itemsep=0pt]
%  \item UK: colour
%  \item US: color
%  \item AU: COLOUR
%  \item CA: COLOR
%  \end{enumerate}
%  By using the four words in the following manner:
%  \begin{verbatim}
%    \vara{colour} \vara{color} \vara{COLOUR} \vara{COLOR}
%  \end{verbatim}
%  and by using various language option with different values for the
%  option \marg{lang}, we can switch across different languages for
%  all four words, no matter, whatever locate spelling one has adopted
%  for the word in the document instance.
%  \begin{enumerate}[itemsep=0pt]
%  \item |lang=uk| $\longrightarrow$ colour colour colour colour
%  \item |lang=us| $\longrightarrow$ color color color color
%  \item \dots 
% \end{enumerate}
%
% \begin{function}{starred \vara}
% If for any reason, the user chooses to retain the word as it is then
% it is possible by using the starred version of the macro:
% \begin{syntax}
%   \cs{vara*}\Arg{word}
% \end{syntax}
% \end{function}
% 
% \subsection{Close-up, Hyphenation, Spaced Words}
%
% \begin{function}{\hyp,\closeup,\sword}
% \begin{syntax}
%   \cs{hyp}\Arg{word}\Arg{word}\\
%   \cs{closeup}\Arg{word}\Arg{word}\\
%   \cs{sword}\Arg{word}\Arg{word}
% \end{syntax}
% \end{function}
% \noindent There are three commands that make the above possible:
%  \begin{enumerate}[itemsep=0pt]
%  \item |\hyp{anti}{body}| $\longrightarrow$ anti-body (hyphenate)
%  \item |\closeup{anti}{body}| $\longrightarrow$ antibody (close up)
%  \item |\sword{Civil}{War}| $\longrightarrow$ Civil War (space our)
%  \end{enumerate}
%  
% \subsection{Latin Abbreviation}
%
% \begin{function}{\definelat,\lat}
%  \begin{syntax}
%    \cs{definelat} \Arg{abbr} \Arg{abbr without dots} \Arg{English form}\\
%    \cs{lat} \Arg{abbr}
%  \end{syntax}
% \end{function}
% \noindent Latin abbreviations can be used in different ways. The
% option |lat=0| will keep the Latin abbreviation as such in form in
% italic shape. |abbr=italic| will make the abbreviation italicized
% (which is also default). |abbr=rm| will make it upshape.  |lat=1|
% will take away the periods in the abbreviated Latin forms while
% |lat=2| will replace the abbreviation with its English language
% equivalents.
%
% The package comes with a default list of abbreviations. Users shall
% use the command \cs{lat}\Arg{abbr} to invoke the desired format of
% abbeviation in the document instance.
%
% 
% \subsection{Acronyms}
%
% \begin{function}{\newacro,\ac}
%  \begin{syntax}
%   \cs{newacro} \Arg{short form} \Arg{long form}\\
%   \cs{ac} \Arg{short form}
% \end{syntax}
% \end{function}
% \noindent The highly aclaimed package, namely, \pkg{acronym} has
% been made use of to achieve the extensive features available
% therein. Kindly refer to its documentation for getting an
% understanding of the usage.
%
% \subsection{Itemization and Non-local Lists}
%
% A list environment, namely, |eitem| has been defined which can be
% used for a variety of purposes as enlisted below by changing its
% options.
% 
% \begin{flushleft}
% \begin{tabular}{@{}ll}
% \bfseries Option &amp; \bfseries Rendering\\[3pt]
% |eitem=0|  &amp; normal list: Firstly, Secondly, Thirdly, \dots\\
% |eitem=1|  &amp; normal list: First, Second, Third, \dots\\
% |eitem=2|  &amp; enumerated list: 1, 2, 3, \dots\\
% |eitem=3|  &amp; itemized bulletted list\\
% |eitem=4|  &amp; para list: Firstly, secondly, thirdly, \dots\\
% |eitem=5|  &amp; para list: First, second, third, \dots\\
% \end{tabular}
% \end{flushleft}
%
% In the para list forms, each item will be separated by semicolon
% (|;|) and the penultimate item will be connected to the last one by
% the `|and|' automatically.
%
% \begin{function}{\elist}
% \begin{syntax}
%  \cs{elist} \Arg{comma separated list}
% \end{syntax}
% \end{function}
% \noindent
% There is also a convenient command, ``|elist|'' that helps to format
% a comma separated list in a proper way with proper spacing.  For
% example,
% \begin{verbatim}
%   \elist{warblers,tits,wrens,hummingbirds}
%   \elist{warblers , tits, wrens ,hummingbirds}
% \end{verbatim}
% will be formatted in the proper way with right spacing and correct
% punctuation:
% \begin{quote}\color{vcolor}
%   warblers, tits, wrens and hummingbirds
% \end{quote}
%
% \subsection{Parenthetical and Serial Comma}
%
% \begin{function}{\pc}
%  \begin{syntax}
%   \cs{pc} \Arg{text to be included}
% \end{syntax}  
% \end{function}
% \noindent This is accomplished with the command \cs{pc} and the text
% to be distiguished shall be its argument. Different values for
% option with the same name, |pc|, provide different functionality as
% detailed below:
% 
% \begin{flushleft}
% \begin{tabular}{@{}ll}
% \bfseries Option &amp; \bfseries Rendering\\[3pt]
% |pc=0|  &amp; argument is separated by parenthetical commas\\
% |pc=1|  &amp; separated by parenthesis\\
% |pc=2|  &amp; separated by emdashes\\
% |pc=3|  &amp; formatted as a footnote \\
% |pc=4|  &amp; formatted as a sidenote (marginpar)
% \end{tabular}
% \end{flushleft}
%
% \subsection{Non-local Tokenization}
%
% \begin{function}{\definetoken,\tkn} 
%  \begin{syntax}
%   \cs{definetoken} \Arg{label} \Arg{full tokens} \Arg{less tokens}
%   \Arg{least tokens} \\
%   \cs{tkn} \Arg{label}
% \end{syntax}  
% \end{function}
% \noindent A sequence of minimization operation can be brought out by
% first defining the tokens to be minimized and then using the same
% consecutively will typeset the tokens in differently and minimized
% manner each time it is called.  We define a token as:
% \begin{verbatim}
%   \definetoken{mango}{His Holyness, the Prince of Mangoistan}
%               {The Prince of Mangoistan}{He}
% \end{verbatim}
% will have different output as given below:
% 
% \begin{flushleft}
% \begin{tabular}{@{}ll}
% \bfseries Command &amp; \bfseries Rendering\\[3pt]
% First instance: \cs{tkn}|{mango}| &amp; His Holyness, the Prince of Mangoistan\\
% Second: \cs{tkn}|{mango}|&amp; The Prince of Mangoistan\\
% Third: \cs{tkn}|{mango}|&amp; He \\
% Fourth: \cs{tkn}|{mango}|&amp; He
% \end{tabular}
% \end{flushleft}

% \begin{environment}{eitem}
%   \env{eitem} is defined to switch between non-local list of
%   different types. We make use of the package \pkg{enumitem} for
%   this purpose.
%
%    \begin{macrocode}
\RequirePackage{enumitem}
\chardef\thre@=3
\newenvironment{enumerate*}[1][]%
     {\@nameuse{enit@enumerate*}\enitdp@enumerate{enum}\thre@{#1}}
     {\@nameuse{enit@endenumerate*}}
%    \end{macrocode}
%
% A few macros like, \cs{lastlabel}, \cs{mysep}, \cs{myseplast},
% \cs{elistcnt}, \cs{LastItem} are defined to make the job easier. 
%
%    \begin{macrocode}
\int_new:N \l@@_elistcnt_int
\NewDocumentCommand \lastlabel { } { \tex_xdef:D\@itemlabel{Lastly}}
\NewDocumentCommand \mysep { } { ;\hskip .5em plus .1em minus .1em  }
\NewDocumentCommand \myseplast { } {\space and \space  }
\NewDocumentCommand \elistcnt { } { \int_use:N \l@@_elistcnt_int }
\NewDocumentCommand \LastItem { m m }
   { \tl_gset:cn { l@@_tmpa_#1_tl } { #2 } }
%    \end{macrocode}
%
% \begin{macro}{\checklast}
% \cs{checklast} is the macro that finds the last item number and
% substitutes with |Last| or |Lastly| depending upon the option
% chosen. 
% 
%    \begin{macrocode}
\NewDocumentCommand \checklast { m }
  {
    \tl_if_exist:cTF { l@@_tmpa_ \elistcnt _tl }

      { \int_set:Nn \l_tmpa_int { 0 } }
    \int_set:Nn \l_tmpb_int { \the\c@enumi }
