% \maketitle
%
% \section{Introduction}
%
% MLA style is ugly.  Nevertheless, it is often required, particularly in
% the humanities.
%
% \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 Futility of Compulsory English Classes}
%
%\begin{document}
%\maketitle
%'Nuff said.
%\end{document}\end{verbatim}
% \subsection{Initiation Macros}
% \DescribeMacro{\maketitle}
% \DescribeMacro{\instructor}
% \DescribeMacro{\course}
% The mandatory heading\index{heading|usage} is generated with
% |\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 |\instructor|\marg{instructor} and
% |\instructor|\marg{course} macros.
%
% \DescribeMacro{\surname}
% The last name for use in the header\index{header|usage} is derived from
% |\author|.  If this does not produce the desired result, use
% |\surname|\marg{last name} to override it.
%
% \DescribeMacro{\date}
% \DescribeMacro{\today}
% MLA style recommends the DD~Mon.~YYYY format for specifying dates;
% |\today| has been conveniently redefined to this.  However, other
% formats can be used as long as done so consistantly throughout the
% document.  Also note that the date in the header should be the due date
% of the assignment, so be sure to explictly call |\date|\marg{due date}
% if you actually finish your assignments early.
%
% \subsection{Environments}
% \DescribeEnv{verse}
% \DescribeEnv{quote}
% \DescribeEnv{quotation}
% Three environments have been modified from standard \LaTeX to better
% suit MLA format.  To typeset poetry\index{poetry|usage} and
% drama\index{drama|usage}, use the |verse| environment.
% Quotations\index{quotations|usage} of a single paragraph or less always
% use the |quote| environment.  For longer passages, use the |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{Documentating Sources}
%
% Coupled with \BibTeX\index{BibTeX\actualchar\BibTeX|usage}
% \package{mlastyle} provides a experimental implementation of MLA
% documentation style.  Put |\bibliographystyle{mlastyle}| in the document
% preamble to load the bibliography style.

% |\citeM| and its ilk will utilize it.
