+% \maketitle
+%
+% \begin{abstract} \TeX\ users have long been remarking that
+% the default characteristics of ellipses, whether produced
+% by |\dots|, |\ldots|, or some other command, just aren't
+% quite right.  While some packages have attempted to
+% resolve this issue (e.g., |lips| and |ellipsis|), these
+% have never quite fit my use cases.  |xellipsis| attempts
+% to fill this gap by providing absurdly configurable
+% ellipses, along with preconfigured options for the Chicago
+% Manual of Style (and Turabian), MLA, and the Bluebook.  \end{abstract}

+%
+% \section{Introduction}
+%
+% Typography has long made use of these strange sequences of
+% (usually) dots called \emph{ellipses} (singular
+% \emph{ellipsis}).  An ellipsis typically indicates an
+% omission from a quotation (indeed, the Greek root means
+% ``omission''), but they have also been used in a huge
+% variety of other ways over the years:
+%
+% \begin{itemize} \item The aforementioned omission.  ``Four
+% score and\xelip seven years ago.'' \item An unfinished
+% thought.  ``Our forefathers brought forth\xelip I don't
+% know; something, I guess.'' \item Indications of preceding
+% matter.  ``\xelip a new nation, conceived in liberty.''
+% \item A pause.  ``I think\xelip therefore, I am.'' \item
+% Probably lots of other things, as well.  \end{itemize}
+%
+% \LaTeX, by default, produces ellipses with the |\dots|
+% (\dots) or |\ldots| (\ldots) commands.  These are fine, as
+% far as they go; however, they suffer a few clear faults.
+% For example, there is much less space at the beginning
+% than at the end, which many people don't like; they are
+% fairly close together, which not only do many people not
+% like, but which goes against some important style manuals;
+% they cannot have four or more dots, which some style
+% manuals require in certain circumstances; and their
+% spacing is not in any way configurable.
+%
+% So |xellipsis| gives you all the configuration options for
+% your ellipses that you could possibly want, and probably
+% lots more than you'll ever need.  It also comes
+% prepackaged with a few common formats, which are selected
+% as package options at load time.
+%
+% |xellipsis| is packaged according to the \LaTeX\
+% \textsc{docstrip} utility, which allows automatic
+% extraction of code and documentation from the same files.
+%
+% \section{Preconfigured Formats}
+% \label{sect:preconf}
+%
+% |xellipsis| comes with some preconfigured ellipsis formats
+% for the convenience of users.  These are all set as
+% package options; so, for example, when loading the package
+% one states |\usepackage{xellipsis}| for the default
+% behavior, but |\usepackage[latex]{xellipsis}| to specify
+% the |latex| format.
+%
+% Please note that the usage of these ellipses is not always
+% clear, even according to the manuals.  I've done my best
+% to get them right here, but if they're wrong on some
+% detail, please let me know and I'll try to fix them.
+% |xellipsis| offers ample configuration options to get
+% these things right.
+%
+% \DescribeMacro{latex}
+% The |latex| option sets up |\xelip| to behave identically
+% to the default \LaTeX\ setting of |\dots| or |\ldots|.
+% (The \LaTeX\ kernel defines |\ldots| as
+% |\let\ldots=\dots|, so the two are the same.)  In a
+% convoluted way, |\dots| is defined in terms of
+% |\textellipsis|, which itself is simply three dots
+% separated by the current font's |\fontdimen3|, which is
+% the stretchability of interword space.  Not the interword
+% space itself, mind you, but just the stretchability of
+% that space.  This leads to pretty tightly spaced ellipses
+% for most fonts; but there we are.  It also specifies no
+% particular space before the ellipsis, but the same space
+% as the gaps afterwards.  This option yields the following:
+%	\begin{quote}
+%		{\xelipbef=0pt\xelipaft=\fontdimen3\font\xelipgap=\fontdimen3\font
+% 		This is\xelip pretty tight, really. (|\xelip|)
+%
+% 		This is\ldots pretty tight, really. (|\ldots|)
+%		}
+%	\end{quote}
+%
+% \DescribeMacro{chicago}
+% \textit{The Chicago Manual of Style} has some very
+% specific rules about ellipses; specifically, that they
+% should be three periods plus two nonbreaking spaces.  So
+% |xellipsis| defines them precisely that way, in terms of
+% |\fontdimen2| (the non-glue portion of the interword space
+% for the font), and adds no space before the first dot.
+% The \textsc{cmos} also specifies that, at the end of a
+% natural sentence, the period of the sentence should remain
+% \emph{prior} to the ellipsis; this works fine with our
+% definition.
+% This system yields:
+%	\begin{quote}
+%		{\xelipbef=0pt\xelipaft=\fontdimen2\font\xelipgap=\fontdimen2\font
+% 		This is\xelip pretty loose, really. (|\xelip|)
+%
+% 		I like that.\ \xelip It makes some sense. (|.\ \xelip|)
+%		}
+%	\end{quote}
+%
+% \DescribeMacro{mla}
+% The \textsc{mla} advises similar ellipses to the \textsc{cmos},
+% except that there should always be a space before the
+% first period.
+%	\begin{quote}
+%		{\xelipbef=\fontdimen2\font\xelipaft=\fontdimen2\font\xelipgap=\fontdimen2\font
+% 		This is\xelip pretty loose, really. (|\xelip|)
+%		}
+%	\end{quote}
+%
+% \DescribeMacro{oldmla}
+% The \textsc{mla} formerly advised that ellipses indicating
+% omissions should be surrounded by square brackets ([]).
+% The materials I've seen seem to indicate that this might
+% still be required when the quotation already contains
+% ellipses in the original material; however, usually they
+% are not required.  Either way, here's the option:
+%	\begin{quote}
+%		{\xelipbef=\fontdimen2\font\xelipaft=\fontdimen2\font\xelipgap=\fontdimen2\font\def\xelipprechar{[}\def\xelippostchar{]}\xelipprebef=\fontdimen2\font\xelippostaft=\fontdimen2\font
+% 		This is\xelip how it's supposed to work, I guess? (|\xelip|)
+%		}
+%	\end{quote}
+%
+% \DescribeMacro{bluebook}
+% Finally, in the United States legal citations are governed
+% by our overlords at the Harvard Law Review, who publish
+% \textit{The Bluebook}.  Their ellipses are formatted just
+% like the \textsc{mla} ellipses:
+%	\begin{quote}
+%		{\xelipbef=\fontdimen2\font\xelipaft=\fontdimen2\font\xelipgap=\fontdimen2\font
+% 		This is\xelip pretty loose, really. (|\xelip|)
+%		}
+%	\end{quote}
+%
+% Finally, there is a special command
+% \DescribeMacro{\xelipend}|\xelipend|.  This is identical
+% to |\xelip| except that the closing space is omitted.
+%
+%	\begin{quote}
+% 		``This is pretty neat\xelipend'' (|\xelipend|)
+%
+% 		``This is pretty neat\xelip'' (|\xelip|)
+%	\end{quote}
+%
+% |\xelipend| is primarily useful immediately preceding some
+% quoting character; some people prefer there to be no or
+% much more limited spacing in this location.  Use
+% |\xelipend| if you prefer this type of behavior.
+%
+% \section{The Nitty-Gritty:  Configuration}
+% \label{sect:nittygritty}
+%
+% We've already seen examples of the |xellipsis| defaults
+% used (any time in this document that we haven't been
+% explicitly demonstrating something else), so let's get
+% down-and-dirty with the internals and do some customizing.
+%
+% The first is the most obvious:  the character from which
+% the ellipsis is constructed.  This defaults to ``.'' (a
+% period), and is held in the variable
+% \DescribeMacro{\xelipchar}|\xelipchar|.  Simply redefine
+% |\xelipchar| in the normal way to get something different
+% from the ordinary:
+%
+% \bigskip \hbox to\linewidth{% \hfil% \hbox
+% to0.4\linewidth{% \hfil% \vbox{%
+% \hbox{|\def\xelipchar{*}|} \hbox{|\xelip|} } \hfil% }\hbox
+% to0.4\linewidth{% \hfil% \vbox{% \def\xelipchar{*}\xelip }
+% \hfil% } \hfil% } \bigskip
+%
+% \def\xelipchar{*} This was actually quite common in older
+% legal documents (using asterisks for ellipses, that is):
+% ``And the ruling of the lower court\xelip is hereby
+% \textsc{affirmed}.'' \def\xelipchar{.}  So this sort of
+% thing has some real functionality at times.
+%
+% The same effect can be achieved by using the
+% \DescribeMacro{char}|char| package option; e.g., by
+% loading |xellipsis| with |\usepackage[char=*]{xellipsis}|.
+% Indeed, as of version 2.0, all these settings can be made
+% at the time of package loading.
+%
+% The \emph{number} of characters in an ellipsis is governed
+% by \DescribeMacro{\xelipnum}|\xelipnum|.   |\xelipnum| is
+% a \emph{counter}, not a macro, so if you change it, do so
+% with a simple |=|:
+%
+% \bigskip \hbox to\linewidth{% \hfil% \hbox
+% to0.4\linewidth{% \hfil% \vbox{% \hbox{|\xelipnum=6|}
+% \hbox{|\xelip|} } \hfil% }\hbox to0.4\linewidth{% \hfil%
+% \vbox{% \xelipnum=6 \xelip } \hfil% } \hfil% } \bigskip
+%
+% Most likely this would be 3 or 4, but I'm not going to try
+% to limit you.  |\xelipnum| defaults to 3.  The package
+% option is \DescribeMacro{num}|num|.
+%
+% There are three lengths responsible for controlling the
+% spacing of the ellipses.  The space \emph{before} the
+% first character of the ellipses is
+% \DescribeMacro{\xelipbef}|\xelipbef|; the space
+% \emph{after} the last character of the ellipses is
+% \DescribeMacro{\xelipaft}|\xelipaft|; and the space
+% \emph{between} the characters of the ellipses is
+% \DescribeMacro{\xelipgap}|\xelipgap|.  Each of these
+% default to |3pt|.  Their package options are
+% \DescribeMacro{before}|before|,
+% \DescribeMacro{after}|after|, and
+% \DescribeMacro{gap}|gap|.
+%
+% The benefit of having each of these independently
+% configurable is that you don't have to worry about
+% inserting special spacing before the ellipsis.
+% Furthermore, you don't have to worry about |\xelip| eating the space
+% after your command unless you prevent that with |{}| or 
+% |\ |; it \emph{does}
+% eat the space, but that's okay, because the appropriate
+% spacing is built into it.  So you can say 
+% |I went\xelip to the store| and you'll get 
+% ``I went\xelip to the store'', exactly as you undoubtedly
+% wanted.  No need for |\xelip{}| or such expedients.
+%
+% Remember that these lengths are |dimen|s, so they are
+% reset using a simple |=|; you can also use the \LaTeX\
+% |\setlength| incantation if you'd prefer:
+%
+% \bigskip
+% \hbox to\linewidth{%
+% 	\hfil%
+% 	\hbox to0.49\linewidth{%
+% 		\hfil%
+% 		\vbox{%
+% 			\hbox{|\xelipbef=1em|}
+% 			\hbox{|\xelipgap=2em|}
+% 			\hbox{|\setlength{\xelipaft}{2pt}|}
+% 			\hbox{|This is\xelip strange.|}
+% 		}%
+% 		\hfil%
+% 	}\hbox to0.49\linewidth{%
+% 		\hfil%
+% 		\vbox{%
+% 			\xelipbef=1em
+% 			\xelipgap=2em
+% 			\setlength{\xelipaft}{2pt}
+% 			This is\xelip strange.
+% 		}
+% 		\hfil%
+% 	}%
+% 	\hfil%
+% }
+% \bigskip
+%
+% Finally, some style guides (including the MLA, until
+% recently) require some surrounding punctuation for an
+% ellipsis.  |xellipsis| provides for this, too.  The
+% character that is to go \emph{before} the ellipsis is
+% \DescribeMacro{\xelipprechar}|\xelipprechar|, while the
+% character that is to go \emph{after} the ellipsis is
+% \DescribeMacro{\xelippostchar}|\xelippostchar|.  Both of
+% these default to be empty.  Their package options are
+% \DescribeMacro{prechar}|prechar| and
+% \DescribeMacro{postchar}|postchar|.
+%
+% \bigskip
+% \hbox to\linewidth{%
+% 	\hfil%
+% 	\hbox to0.49\linewidth{%
+% 		\hfil%
+% 		\vbox{%
+% 			\hbox{|\def\xelipprechar{[}|}
+% 			\hbox{|\def\xelippostchar{]}|}
+% 			\hbox{|This is\xelip strange.|}
+% 		}%
+% 		\hfil%
+% 	}\hbox to0.49\linewidth{%
+% 		\hfil%
+% 		\vbox{%
+% 			\def\xelipprechar{[}
+% 			\def\xelippostchar{]}
+% 			This is\xelip strange.
+% 		}
+% 		\hfil%
+% 	}%
+% 	\hfil%
+% }
+% \bigskip
+%
+% As with |\xelipchar|, you can use really anything for
+% this, even things that would be truly bizarre (daggers?
+% fleur-de-lis?); but this is a typical use case.
+%
+% The unsurprisingly-named
+% \DescribeMacro{\xelipprebef}|\xelipprebef|,
+% \DescribeMacro{\xelippreaft}|\xelippreaft|,
+% \DescribeMacro{\xelippostbef}|\xelippostbef|, and
+% \DescribeMacro{\xelippostaft}|\xelippostaft| control the
+% spacing around these two characters; by default, all four
+% are set to |0pt|.  They are |dimen|s and can be set in
+% either the \TeX\ way or the \LaTeX\ |\setlength| way.
+% Their package options are
+% \DescribeMacro{prebefore}|prebefore|,
+% \DescribeMacro{preafter}|preafter|,
+% \DescribeMacro{postbefore}|postbefore|, and
+% \DescribeMacro{postafter}|postafter|,
+%
+% \bigskip
+% \hbox to\linewidth{%
+% 	\hfil%
+% 	\hbox to0.49\linewidth{%
+% 		\hfil%
+% 		\vbox{%
+% 			\hbox{|\def\xelipprechar{[}|}
+% 			\hbox{|\def\xelippostchar{]}|}
+% 			\hbox{|\xelipprebef=6pt|}
+% 			\hbox{|\xelippreaft=3pt|}
+% 			\hbox{|\setlength{\xelippostbef}{3pt}|}
+% 			\hbox{|\setlength{\xelippostaft}{6pt}|}
+% 			\hbox{|This is\xelip strange.|}
+% 		}%
+% 		\hfil%
+% 	}\hbox to0.49\linewidth{%
+% 		\hfil%
+% 		\vbox{%
+% 			\def\xelipprechar{[}
+% 			\def\xelippostchar{]}
+% 			\xelipprebef=6pt
+% 			\xelippreaft=3pt
+% 			\setlength{\xelippostbef}{3pt}
+% 			\setlength{\xelippostaft}{6pt}
+% 			This is\xelip strange.
+% 		}
+% 		\hfil%
+% 	}%
+% 	\hfil%
+% }
+% \bigskip
+%
+% Please be aware that |\xelippreaft| \emph{stacks}
+% with |\xelipbef|, and |\xelippostbef| stacks with
+% |\xelipaft|; so their sum should be the spacing you want.
+% Often this means simply leaving the two of them alone, as
+% you've already got the appropriate space in the
+% shorter-named |dimen|s.
+%
+% And that's it; if |xellipsis| can't meet your ellipsis
+% needs somehow, please contact me and let me know, and I'll
+% endeavor to add what you require.  Happy \TeX{}ing!
+%
+% \section{Implementation}
+%
+% Our first task, as usual, is to define our options.  We
+% have options for default \LaTeX\ ellipsis behavior,
+% Chicago Manual of Style behavior, old MLA behavior, and
+% current MLA behavior.  These all default to \emph{off},
+% and the default |xellipsis| behavior described above is
+% \emph{on}.  We define the conditions for the options, then
+% process the options themselves.  We use |xkeyval| to get
+% these options, so we can easily give them key-value
+% arguments.  We also need to define our default characters.
+%    \begin{macrocode}
+\RequirePackage{xkeyval}
+\def\xelipchar{.}
+\def\xelipprechar{}
+\def\xelippostchar{}
+%    \end{macrocode}
+% Proceed to define the dimens that we will need.  These are
+% mostly self-explanatory; the first is for the gap
+% between the characters of the ellipsis, the second is for
+% the space \emph{before} the ellipsis begins, and the third
+% is for the space \emph{after} the ellipsis ends.  The
+% fourth and fifth are for the spaces around the
+% pre-ellipsis character, and the sixth and seventh are for
+% the spaces around the post-ellipsis character.
+%    \begin{macrocode}
+\newdimen\xelipgap\xelipgap=3pt
+\newdimen\xelipbef\xelipbef=3pt
+\newdimen\xelipaft\xelipaft=3pt
+\newdimen\xelipprebef\xelipprebef=0pt
+\newdimen\xelippreaft\xelippreaft=0pt
+\newdimen\xelippostbef\xelippostbef=0pt
+\newdimen\xelippostaft\xelippostaft=0pt
+%    \end{macrocode}
+% Now we define the counter which holds the number of
+% ellipsis characters we want.  Defaults to 3.
+%    \begin{macrocode}
+\newcount\xelipnum\xelipnum = 3%
+%    \end{macrocode}
+%    \begin{macrocode}
+\newif\ifxel@latex\xel@latexfalse
+\newif\ifxel@chicago\xel@chicagofalse
+\newif\ifxel@oldmla\xel@oldmlafalse
+\newif\ifxel@mla\xel@mlafalse
+\newif\ifxel@bluebook\xel@bluebookfalse
+\DeclareOptionX{latex}{\xel@latextrue}
+\DeclareOptionX{chicago}{\xel@chicagotrue}
+\DeclareOptionX{oldmla}{\xel@oldmlatrue}
+\DeclareOptionX{mla}{\xel@mlatrue}
+\DeclareOptionX{bluebook}{\xel@bluebooktrue}
+\DeclareOptionX{char}{\def\xelipchar{#1}}
+\DeclareOptionX{num}{\xelipnum=#1}
+\DeclareOptionX{before}{\xelipbef=#1}
+\DeclareOptionX{after}{\xelipaft=#1}
+\DeclareOptionX{gap}{\xelipgap=#1}
+\DeclareOptionX{prechar}{\def\xelipprechar{#1}}
+\DeclareOptionX{postchar}{\def\xelippostchar{#1}}
+\DeclareOptionX{prebefore}{\xelipprebef=#1}
+\DeclareOptionX{preafter}{\xelippreaft=#1}
+\DeclareOptionX{postbefore}{\xelippostbef=#1}
+\DeclareOptionX{postafter}{\xelippostaft=#1}
+\ProcessOptionsX
+%    \end{macrocode}
+% Now we define the loop variable.
+%    \begin{macrocode}
+\newcount\xel@loopi\xel@loopi = 0%
+%    \end{macrocode}
+% Next, we define the box which will hold the ellipsis; this
+% way we can be sure that it won't break across lines.
+%    \begin{macrocode}
+\def\xelip{%
+	\nobreak\hskip0pt\hbox{%
+%    \end{macrocode}
+% Put it the code for the |\xelipprechar| and its spacing:
+%    \begin{macrocode}
+		\hskip\xelipprebef\xelipprechar\hskip\xelippreaft%
+%    \end{macrocode}
+% Now, we use |\xelipbef| to skip the pre-ellipsis distance.
+%    \begin{macrocode}
+		\hskip\xelipbef\xelipchar%
+%    \end{macrocode}
+% Now we loop, printing |\xelipchar| and skipping
+% |\xelipgap| as many times as |\xelipnum| requires.  We
+% start be resetting the |\xel@loopi| variable, just in
+% case.
+%    \begin{macrocode}
+		\xel@loopi = 1%
+		\loop\ifnum\xelipnum>\xel@loopi%
+			\advance\xel@loopi by1%
+			\hskip\xelipgap%
+			\xelipchar%
+		\repeat
+%    \end{macrocode}
+% Lastly, we skip |\xelipaft|, then skip for
+% |\xelippostchar| and its |dimen|s, close our box, and sit
+% back in the satisfaction of an ellipsis well-made.
+%    \begin{macrocode}
+		\hskip\xelipaft%
+		\hskip\xelippostbef\xelippostchar\hskip\xelippostaft%
+	}%
+}%
+%    \end{macrocode}
+% Set up a special command, |\xelipend|, which omits the
+% spacing at the end and can be used immediately before
+% quotations or the like.
+%    \begin{macrocode}
+\def\xelipend{%
+	\begingroup%
+	\xelipaft=0pt
+	\xelip%
+	\endgroup%
+}%
+% 
+% Set up the |latex| option.
+%    \begin{macrocode}
+\ifxel@latex
+	\xelipbef=0pt%
+	\xelipaft=\fontdimen3\font%
+	\xelipgap=\fontdimen3\font%
+\fi
+%    \end{macrocode}
+% \textit{The Chicago Manual of Style} option.
+%    \begin{macrocode}
+\ifxel@chicago
+	\xelipbef=0pt%
+	\xelipaft=\fontdimen2\font%
+	\xelipgap=\fontdimen2\font%
+\fi
+%    \end{macrocode}
+% The \textsc{mla} option.
+%    \begin{macrocode}
+\ifxel@mla
+	\xelipbef=\fontdimen2\font%
+	\xelipaft=\fontdimen2\font%
+	\xelipgap=\fontdimen2\font%
+\fi
+%    \end{macrocode}
+% \textit{The Bluebook} option.
+%    \begin{macrocode}
+\ifxel@bluebook
+	\xelipbef=\fontdimen2\font%
+	\xelipaft=\fontdimen2\font%
+	\xelipgap=\fontdimen2\font%
+\fi
+%    \end{macrocode}
+% The old \textsc{mla} option.
+%    \begin{macrocode}
+\ifxel@oldmla
+	\xelipbef=\fontdimen2\font%
+	\xelipaft=\fontdimen2\font%
+	\xelipgap=\fontdimen2\font%

+	\xelipprebef=\fontdimen2\font%
+	\xelippostaft=\fontdimen2\font%
+\fi
+%		}
+%    \end{macrocode}
+% And there's the |xellipsis| package.  I hope it proves
+% useful to someone besides myself.  Happy \TeX{}ing!
