% \section{Introduction}
%
% MLA style, consisting of a set of documentation conventions, has
% gained widespread acceptance in the humanities.  \LaTeX{} is a
% document preparation system enjoying popularity in the scientific field.
% It should come as no surprise that complete, up-to-date implementations
% of MLA style for \LaTeX{} are in short supply.  The \LaTeX{} package
% \package{mlastyle} aims to fill this void.
%
% \section{Usage}
%
% A sample document follows.
% \begin{verbatim}
%\documentclass[12pt]{article}
%\usepackage{mlastyle}
%
%\author{John Doe}
%\instructor{Professor Smith}
%\course{English 101}
%\date{1~Jan.\ 1970}
%\title{The Inherent Sadism of Compulsory English Classes}
%
%\begin{document}
%\maketitle
%'Nuff said.
%\end{document}\end{verbatim}
% \subsection{Initialization Macros}
% The \index{heading|usage}mandatory heading is generated with
% \DescribeMacro{\maketitle}|\maketitle|.  Use the standard macros
% |\author|, |\title|, and |\date| to specify the relevant information.
% To define the instructor and name of the course, use the aptly named
% \DescribeMacro{\instructor}|\instructor|\marg{instructor} and
% \DescribeMacro{\course}|\course|\marg{course} macros.
%
% The last name for use in the header\index{header|usage} is derived from
% |\author|.  If this does not produce the desired result, use
% \DescribeMacro{\surname}|\surname|\marg{last name} to override it.
%
% MLA style recommends the DD~Mon.~YYYY format for specifying dates;
% \DescribeMacro{\today}|\today| has been conveniently redefined to this.
% However, other formats can be used as long as done so consistently
% throughout the document.  Also note that the date in the
% heading\index{heading|usage} should be the due date of the assignment;
% students who finish assignments early would be wise to call
% |\date|\marg{due date}.
%
% \subsection{Environments}
% Three environments have been modified from standard \LaTeX to better
% suit MLA format.  To typeset \index{poetry|usage}poetry and
% \index{drama|usage}drama, use the \DescribeEnv{verse}|verse|
% environment.  Quotations\index{quotations|usage} of a single paragraph
% or less always use the \DescribeEnv{quote}|quote| environment.  For
% longer passages, use the \DescribeEnv{quotation}|quotation| environment
% if the beginning of the passage marks the beginning of a paragraph.
% Otherwise, use the |quote| environment.
%
% Be sure to follow MLA guidelines when using these environments.  Short
% quotes should be enclosed in quotation marks and included directly in
% the text.
%
% \subsection{Modes of Operation}
% The \package{mlastyle} package has four basic modes of operations,
% selected with one of four mutually exclusive options.  The
% \OptionIndex{format}\Lopt{format}
% option tells \package{mlastyle} to use MLA format (i.e., 1 inch margins,
% double-spaced, etc.).  The \OptionIndex{style}\Lopt{style} option tells
% \package{mlastyle} to use MLA style (i.e., the format of parenthetical
% documentation, etc).  Each of these options
% disables the other; to use both MLA format and MLA style, specify the
% \OptionIndex{mla}\Lopt{mla} option, or nothing at all.
%
% To disable both MLA style and MLA format, use the
% \OptionIndex{compat}\Lopt{compat} option.  This differs from omitting
% the package entirely in that certain macros are still defined (e.g.,
% |\instructor|).  Also, citations are handled a bit differently than in
% standard \LaTeX{} (see section~\ref{sec:documentation}).
%
% In addition to the above, several other options modify the behavior of
% \package{mlastyle}.
%
% \subsubsection{Italics vs.\ Underlining} \index{underlining|usage}
% \index{italics|usage}
% MLA format dictates that emphasis should be indicated by underlining the
% text.  Thus, the \package{ulem} package, which underlines all emphasized
% text, is loaded by default in \Lopt{mla} and \Lopt{format} modes.  To
% disable this, use the \OptionIndex{italics}\Lopt{italics} option.
% Conversely, if underlining is desired in \Lopt{style} or \Lopt{compat}
% mode, the \OptionIndex{underline}\Lopt{underline} option can be used.
%
% \subsubsection{Fonts}
% By default, \package{mlastyle} uses \TeX's standard Computer Modern
% font.  Some profess\-ors\penalty500---particularly those
% concerned with document length---require assignments to be set in
% \examp[.]{Times New Roman}  This can be achieved with the
% \OptionIndex{times}\Lopt{times} option, which simply loads the
% \package{times} package.  This opposite of this option is
% \OptionIndex{cm}\Lopt{cm}, which reverts to Computer Modern.
%
% \index{works cited|usage}
% \subsection{Documenting Sources} \label{sec:documentation}
%
% The \package{mlastyle} package reimplements the
% \DescribeEnv{thebibliography}|thebibliography| environment to generate
% the list of works cited in MLA style.  Instruction in the basic use of
% \LaTeX's bibliography features is beyond the scope of this document;
% however, the following example, which should be included just before
% |\end{document}|, might prove to be a useful starting point:
%\begin{verbatim}
%\begin{thebibliography}{}
%
%\bibitem[Lamport]{latex}
%Lamport, Leslie.
%\newblock {\em \LaTeX: A Document Preparation System}.
%\newblock 2nd.~ed.
%\newblock Reading: Addison-Wesley, 1994.
%
%\end{thebibliography}\end{verbatim}
%
% In this example, |Lamport| is the author's last name (for use in
% citations) and |latex| is the marker used to reference it (see
% section~\ref{sec:parenthetical}).
%
% For information on automatically generating the list of works cited with
% \BibTeX, see section~\ref{sec:bibtex}.
%
% \subsubsection{Parenthetical Documentation} \label{sec:parenthetical}
% A simple citation can by achieved with a call to
% \DescribeMacro{\cite}|\cite|\oarg{pages}\marg{marker}, where
% marker refers to the key given to either
% \index{BibTeX=\BibTeX|usage}\BibTeX{} or the |\bibitem| macro (|latex|
% in the above example).
% Omit \oarg{pages} if the source has no page numbers.
% Multiple sources can be cited using the syntax
% |\cite|\oarg{pages}|{|\meta{marker
% 1}\texttt{,}\penalty\exhyphenpenalty\meta{marker 2}\ldots|}|; however, page
% numbers can currently be specified only for the last referenced source.
% To work around this limitation |\citeN|, explained below, can be used.
%
% Three additional citation commands are provided, all of which take the
% same arguments as |\cite|.  To omit the author information from the
% citation, use \DescribeMacro{\citepage}|\citepage|.  Indirect
% citations---those of the format \examp{(qtd. in Brown 6)}---can be
% created with \DescribeMacro{\citeindirect}|\citeindirect|.  Finally, the
% parentheses are omitted by \DescribeMacro{\citeN}|\citeN|.  This was
% intended for use in cross references, but it can also help in citing
% multiple works.  The result of
% |(\citeN[42]{knuth}|\texttt{; }|\citeN[69]{lamport})|
% would be something like \examp[.]{(Knuth 42; Lamport 69)}
%
% \subsubsection{Using {\rm \BibTeX}} \label{sec:bibtex}
% Coupled with \index{BibTeX=\BibTeX|usage}\BibTeX,
% \package{mlastyle} provides a experimental implementation of MLA
% documentation style.  Put\SpecialUsageIndex{\bibliographystyle}
% |\bibliographystyle{mlastyle}| in the document preamble to load the
% bibliography style.  Alternatively, the
% \OptionIndex{bibstyle}\Lopt{bibstyle} option can handle this
% automatically, loading a bibliography style of |mlastyle| in \Lopt{mla}
% and \Lopt{style} modes and a bibliography style of |plain| in
% \Lopt{format} and \Lopt{compat} modes.
%
% Use of \BibTeX{} is also beyond the scope of this document; instead,
% another example is provided.  To use it, substitute
% |\bibliography|\marg{filename} for the |thebibliography| environment.
% Then create \meta{filename}\file{.bib} with the contents below.
% Generating the document entails running \file{latex} on the \file{.tex}
% file, \file{bibtex} on the resulting \file{.aux} file, then \file{latex}
% twice more.
%\begin{verbatim}

%  AUTHOR = "Leslie Lamport",

%  KEY = "\LaTeX",
%  EDITION = "Second",
%  ADDRESS = "Reading",

%  YEAR = "1994"}\end{verbatim}
% In \package{mlastyle}, The |KEY| field serves the additional purpose of
% specifying an abbreviated title.  This is unnecessary in the above
% example.  If an additional book by Leslie Lamport was included, however,
% the |KEY| field would allow |\cite{lamport}| to yield \examp{(Lamport,
% \emph{\LaTeX\/})} instead of \examp[.]{(Lamport, \emph{\LaTeX: A Document
