%
% You have done all the research.  The ideas are in your
% head.  All you are missing is that little thing called a
% dissertation, which you are gung-ho on writing using \LaTeX. This is
% where this class file enters: it allows you to use \LaTeX\ while
% adhering to the formatting guidelines of Brandeis University
% Graduate School of Arts and Sciences (GSAS).   In
% particular, it allows you to get the front matter correct.
%
% The features are as follows:
% \begin{itemize}
% \item It provides correct margins for either single-paged
%   output or double-paged output.
% \item It typesets the text with double-spaced line.  However, footnotes,
%   long quotations (the environment "quotation"), the bibliography, and
%   the index is singe-spaced.
% \item It provides commands to produce the front matter.
% \end{itemize}
%
% To use the class, you should begin your document file with
% \begin{verbatim}
% \documentclass{brandeis-dissertation}\end{verbatim}
% instead of your usual document class declaration.  The various
% options are described below in section~\ref{sec:class-options}.
%
% \section{Front Matter}
%
% The front matter is all the pages that comes before the main text of
% your dissertation, e.g., title page, dedication, abstract, table of
% contents. For the class to typeset the front matter, you should
% specify the formalities regarding your dissertation in the preamble
% of your document.  You do this with the following commands.
% \begin{description}
% \item[\cmd{\title}\marg{title}:]\DescribeMacro{\title}
%    The title of your dissertation.
% \item[\cmd{\author}\marg{name}:]\DescribeMacro{\author}
%   Your full name. 
% \item[\cmd{\department}\marg{department}:]\DescribeMacro{\department}
%   Your department.
% \item[\cmd{\advisor}\meta{advisor}:]\DescribeMacro{\advisor}
%    The full name of you advisor (chair of your
%   committee) . 
% \item[\cmd{\reader}\meta{reader}:]\DescribeMacro{\reader} Adds
%   \meta{reader} to your committee.  You should have one
%   \cmd{\reader}-command for each reader on the committee. You should
%   provide them in the order you want them to appear on the signature
%   page. You should also include the school and department of every 
%   reader.
% \item[\cmd{\dean}\meta{name}:]\DescribeMacro{\dean}
%    The full name of the dean who eventually
%   signs off on the dissertation.
% \item[\cmd{\graduationyear}\meta{year}:]\DescribeMacro{\graduationyear}
%    The year of your dissertation.
% \item[\cmd{\graduationmonth}\meta{month}:]\DescribeMacro{\graduationmonth}
%    The month of your dissertation.
% \item[\cmd{\othercopyright}\meta{text} (optional):] Uses \meta{text}
%   to  acknowledge other people's copyright on your copyright page.
%   This is only printed if you print a copyright page.
% \end{description}
% As an example, the following is an except from the preamble of my
% dissertation:
% \begin{verbatim}
% \title{Complexity Aspects of Programming Language Design}
% \author{Peter M{\o}ller Neergaard}
% \dean{Adam B. Jaffe}
% \advisor{Harry G. Mairson}
% \department{Michtom School of Computer Science}
% \reader{Peter Clote}
% \reader{Simone Martini}
% \reader{Timothy J. Hickey}\end{verbatim}
%
% \DescribeMacro{\thesisfront}The command
% \cmd{\thesisfront}\oarg{options} should be used at the very
% beginning of your document to produce all the front
% matter for you, e.g.,
% \begin{verbatim}
% \begin{document}
% \thesisfront\end{verbatim}
% 
% You need to specify the abstract and possible also the preface,
% dedication, and acknowledgments using the following commands:
% \begin{description}
% \item[\mcmd{\thesisabstract}\marg{text}:]\DescribeMacro{\thesisabstract}
%    Uses \meta{text} as your abstract.
% \item[\mcmd{\dedication}\marg{dedication} (optional):]\DescribeMacro{\dedication}
%    The dedication of your dissertation to \meta{dedication} appears
%    on separate page. 
% \item[\mcmd{\acknowledgments}\marg{text}
%   (optional):]\DescribeMacro{\acknowledgments}
%   \meta{text} is used as your acknowledgment.
% \item[\cmd{\preface}\marg{text} (optional):]\DescribeMacro{\preface}
%    The preface of your dissertation.
% \end{description}
% As the abstract, preface and acknowledgments might by fairly long,
% it can be convenient to keep them in a separate file and include
% them using \cmd{\input}, e.g.
% \begin{verbatim}
%   \thesisabstract{\input{abstract}}\end{verbatim}
% where the abstract in stored in the file "abstract.tex".
%
% \label{p:thesisfront-options}
% You can fine tune the behavior of \cmd{\thesisfront} with the following
% options.  You provide them in an optional argument as a
% comma-separated list:
% \begin{description}
% \item[\texttt{onlinesubmission}:] The signature page is typeset for
%   online submission (default).
% \item[\texttt{papersubmission}:] The signature page is typeset for
%   paper submission.
% \item[\texttt{copyright}:] Print a copyright page (default).
% \item[\texttt{nocopyright}:] Do not print a copyright page.
% \item[\texttt{lot}:] Print a list of tables.
% \item[\texttt{nolot}:] Do not print a list of tables (default)
% \item[\texttt{lof}:]  Print a list of figures.
% \item[\texttt{nolof}:] Do not print a list of figures (default).
% \end{description}
% For instance, the command to produce the front matter for a paper
% submission with a list of tables is:
% \begin{verbatim}
% \thesisfront[lot,papersubmission]\end{verbatim}
%
% \DescribeMacro{\signaturepage}
% When submitting online, you need to produce a signature page to be
% signed before your defense.  You can do this using "\signaturepage*"
% in front of \cmd{\thesisfront} sometimes before you make the final
% version. 
% 
% \subsection{Your Own Front Matter Layout}
%
% Instead of using \cmd{\thesisfront} to produce the front matter, you
% can build the front matter yourself with the command below.
% \emph{However, this option is not recommended and you should ensure
% that you adhere to all the GSAS guidelines}.
%
% \begin{description}
% \item[\mcmd{\thesistitlepage}:]\DescribeMacro{\thesistitlepage} This
%   command produces the front page of your dissertation.
%
% \item[\mcmd{\signaturetitlepage}\ostar:]\DescribeMacro{\signaturepage} 
%   This produces a signature page.  The unstarred version is for
%   online submission, while the starred version is for paper submission.
%
% \item[\mcmd{\copyrightpage}\marg{your name}\marg{year}:]
%   \DescribeMacro{\copyrightpage} This produces the copyright page.
%
% \item[\mcmd{\dedicationpage}\marg{dedication}:] 
%   \DescribeMacro{\dedicationpage}This produces a page with the
%   dedication. 
% \end{description}
%
% \DescribeEnv{optionalpage} 
% \DescribeEnv{optionalpage*}
% The environments  "optionalpage" and "optionalpage*" produce other
% parts of the front matter, for instance the preface.  The part will
% be typeset as if it was a chapter.  They take the title of the part
% as a single argument.  You can thus produce a preface as follows:
% \begin{alltt}\cs{begin}\{optionalpage\}\{Preface\}\par  \(...\)\par\cs{end}\{optionalpage\}\end{alltt}
% By default an entry is added to the table of contents.  This can be
% disabled by using the starred form.
% 
% When printing double-sided, you might \cmd{\cleardoublepage} to
% get the pages positioned on a right hand side.
%
% \section{Margins and Line-spacing}
%
% \begin{table}
% \caption{The two options for margins}
% \begin{tabular}{l|r|r}
%                  & Minimum margins & Consistent 1.5in \\\hline        
%    Left margin   &  1in         & 1.5in \\         
%    Right margin  &  1in           & 1.5in \\
%    Top margin    &  1in           & 1.5in \\
%    Bottom margin &  1in           & 1.5in 
% \end{tabular}
% \label{tbl:margins}
% \end{table}
%
% The GSAS guidelines call for the minimum margins given in
% Table~\ref{tbl:margins}.  This is the default margins for the
% class.  If you prefer, you can get a consistent 1.5in
% margins by using the class option "15margins" (see below).
%
% The class uses the package \package{geometry} to set the
% margins. This provides a very simple way to change the paper layout,
% e.g., to change the margins to 2 inches you just need to use:
% \begin{verbatim}
%   \geometry{top=2in, bottom=2in, left=2in, right=2in }\end{verbatim}
% Note that the \cmd{\geometry} can only be used only in the document
% preamble.  
%
% By default, the dissertation class uses page style "brandeisheadings". This page style will place
%  the page number, centered, in 
% the footer.  If
% you change the page style (to "headings" or "myheadings") in the preamble, the dissertation class
% will adjust the margins accordingly.  However, if you use a
% non-standard heading (for instance from \package{fancyhdr}) you will
% need to adjust the margins accordingly.
% 
% \DescribeEnv{singlespacing}You can use the environment
% "singlespacing" to single-space a block of text.
%
% \section{Class Options}
% \label{sec:class-options}
% 
% The class takes the following options provided as optional arguments
% to the \cmd{\documentclass} command:
% \begin{description}
% \item[\texttt{minmargins}:]  Use the minimum margins called for by
%   GSAS (default).
% \item[\texttt{15margins}:] Use a consistent 1.5in margin.
% \item[\texttt{oneside}:] Single-sided output (from \package{book}
%   class, default). 
% \item[\texttt{twoside}:] Double-sided output.  This gives  different
%   headers on left and right pages.  Some pages might be left blank to have
%   chapters start on right pages (from the \package{book} class).
%
%   You are prone to get some overfull
%   \cmd{\vbox} warnings when using this option.\footnote{With
%     double-sided printing, \LaTeX\ attempts to fill every page to 
%     the bottom to avoid ragged bottoms.  Its main remedy for this is
%     to stretch the spacing between paragraphs.  When this does not
%     provide enough extra space, you get an underfull \cmd{\vbox}.}
%   They can be avoided  by using \cmd{\raggedbottom}, but the result
%   can be very aesthetically unpleasant as you get facing pages with
%   different text height.  Therefore, you are recommended to ignore
%   the overfull boxes if you cannot rearrange the paragraphs to avoid
%   them. 
%
% \item[\texttt{draft}:] Draft version---this marks overfull boxes and might
%   also effect other packages (from the \package{book} class).
% \item[\texttt{final}:] Final version (from the \package{book} class, default).
% \item[\texttt{openright}:] For double-sided printing: chapters
%   always open on the right page (from the \package{book} class, default).
% \item[\texttt{openany}:] For double-sided printing: chapters can
%   open on either a  left or a right page (from the \package{book} class).
% \item[\texttt{blankcleared}:] For double-sided printing: when a page
%   is cleared to make a chapter start on a right page, leave out page
%   number and headers.
% \item[\texttt{numbercleared}:]For double-sided printing: when a page
%   is cleared to make a chapter start on a right page, put page
%   number and headings on the cleared page.
% \item[\texttt{leqno}:] Equation number are placed to the left (from
%   \package{book} class). 
% \item[\texttt{fleqno}:] Equation number are placed flushed to the
%   left (from the \package{book} class).
% \item[\texttt{openbib}:] A more open layout of the bibliography (from the \package{book} class).
% \item[\texttt{12pt}:] The main text is set in 12pt font size (from the \package{book} class, default)
% \item[\texttt{11pt}:] The main text is set in 11pt font size;
%   \cmd{\small} and \cmd{\footnotesize} do not change the font size
%   (essentially from the \package{book} class, \emph{not recommended by
%   GSAS).} 
% \item[\texttt{10pt}:] The main text is set in 11pt font size;
%   \cmd{\small} and \cmd{\footnotesize} do not change the font size
%   (essentially from the \package{book} class, \emph{not recommended by
%   GSAS).}
% \end{description}
%
% \section{Issues To Be Aware Of} 
%
% The following is a list of issues you should be aware.  It might be
% a little {\TeX}nichal so skip it, if it does not apply to your
% dissertation.
%
% \subsection{Margin Notes}
%
% While the class  allows margin notes set with the \LaTeX\ command
% \cmd{\marginpar}, the margins are not designed for margin
% notes. 
% 
% If you use margin notes they will comes as close as  .35in from the
% border of the paper.  If you use them extensively, this is unlikely to
% be kosher and you should adjust the margin parameters.  You can
% solve this by including the following in your preamble.
% \begin{alltt}\cs{geometry}\{marginparwidth=\(w\), marginparsep=\(s\), includemp\}\end{alltt}
% where~$w$ is the width of your margin notes and $s$ their separation
% from the text
%
% You should check with the GSAS for more guidance.  
%
% \StopEventually{}
%
% \section{Driver Producing Documentation}
% 
% We want to  distribution  the documented class file as a single
% file even though the file is used for two very different purposes:
% \begin{enumerate}
% \item \label{it:documentation}To produce the documentation of the class.
% \item \label{it:class}To provide the class for users.
% \end{enumerate} 
% We accomplish this with a bit of code taken from the
% \package{doc} package: We test whether a \cmd{\documentclass}-command has
% already been processed (we exploit that \LaTeX\ binds
% \cmd{\documentclass} to \cmd{\@twoclasseserror} when it start to
% process \cmd{\documentclass}).  If so, we know that we are in
% Case~\ref{it:class}, otherwise we use the driver to produce the
% documentation.
%
% This is implemented with the following trickery.  If the condition
% below is false, i.e., \cmd{\documentclass} is not bound ot
% \cmd{\@twoclasseserror}, then a \cs{fi} is constructed on the fly
% and \LaTeX\ continues processing the code following "\csname fi\endcsname".  On the other hand, if the condition is true, \LaTeX\
% searches for a \cs{fi}, but has no clue that "\csname fi\endcsname" 
% stands for \cs{fi}.  Therefore, it skips until it finds the
% \cs{fi} following "\end{document}".  
%
% Additionally, these parts are enclosed in a guard "gobble" to
% prevent the trickery to end up in files coming out of
% \package{docstrip}. 
%    \begin{macrocode}
%<*driver>
%<*gobble>
\makeatletter
\ifx\documentclass\@twoclasseserror
\else \makeatother\csname fi\endcsname
%</gobble>
%    \end{macrocode}
% Otherwise we process the following lines which will produced the 
% formatted the documentation.  
%
%    \begin{macrocode}
\documentclass{ltxdoc}
\usepackage{url}
\usepackage{alltt}
%    \end{macrocode}
% By default we only want the user documentation:
%    \begin{macrocode}
 \OnlyDescription % Comment this line out for full documentation
%    \end{macrocode}
%  For the full documentation, the following lines should be uncommented:
%    \begin{macrocode}
 % \EnableCrossrefs % Uncomment for full documentation
 % \RecordChanges 
%    \end{macrocode}
% which produces a cross-referenced index of the macros' definitions
% and usage and a history of changes.
% 
% We tell the user not to worry about underfull/overfull boxes.
%    \begin{macrocode}
 \typeout{Expect some Under- and overfull boxes}
%    \end{macrocode}
% Finally, we define some commands to typeset the documentation: First, a
% command to typeset the RCS tags generated by the version control.
% \begin{macro}{\RCS}
%   \mcmd{\RCS}"$"\meta{ID}": "\meta{description}" $" defines
%   \cs{RCS\meta{ID}} to expand to \meta{description}.

% 
% \begin{macro}{\cmd}
% \begin{macro}{\mcmd}
% \begin{macro}{\mcs}
% \begin{macro}{\marg}
% \begin{macro}{\ostar}
% \begin{macro}{\package}
% Second, some commands for formatting the various parts of the
% documentation: We fix the \cmd{\cmd} so it includes "@" in the
% command names (necessary when we define commands \cs{if@$\ldots$}),
% \cmd{\mcmd}\marg{\cs{command}} for the mandatory command name set as
% with \cmd{\cmd}, \cmd{\mcs}\marg{name} for the mandatory command
% name set as with \cmd{\cs}, \cmd{\marg}\marg{argument} for a
% mandatory argument, \cmd{\ostar} for an optional start, and
% \cmd{\package}\marg{package name} for a package name.

% \subsection{Spacing}
%
%  From the Brandeis web page: ``Double-space all textual material and
%  all preliminary pages.''. Switching between single and double
%  spacing can be painful, but the package \package{setspace} takes
%  out most of the sting.
%    \begin{macrocode}
\RequirePackage[doublespacing]{setspace}
%    \end{macrocode}
%
%  From the Brandeis web page: ``Notes, bibliographic references, and
%  long quotations may be single-spaced.''.  
%
% \begin{environment}{thebibliography}
% \begin{environment}{theindex}
% \begin{environment}{quotation}
% \begin{macro}{\bd@thebibliography}
% \begin{macro}{\bd@endthebibliography}
% \begin{macro}{\bd@theindex}
% \begin{macro}{\bd@endtheindex}
% \begin{macro}{\bd@quotation}
% \begin{macro}{\bd@endquotation}
%    \package{setspace} is smart enough to single-space footnotes for
%    you.  We adapt
%    the bibliography, index, and "quotation" environment\footnote{From the
%    \LaTeX-book: ``The "quotation" environment is used for quotations
%    of more than one paragraph''} to produce single-spaced output:
%    \begin{macrocode}
\let\bd@thebibliography\thebibliography
\let\bd@endthebibliography\endthebibliography
\renewenvironment{thebibliography}%
    {\begin{singlespace}\bd@thebibliography}%
  {\bd@endthebibliography\end{singlespace}}

    {\begin{singlespace}\bd@quotation}%

% \end{macro}^^A \bd@thebibliography
% \end{environment}^^A quotation
% \end{environment}^^A theindex
% \end{environment}^^A thebibliography
%
% Finally, we also decrease the line spacing smaller in math displays
% as displays otherwise look odd.
%    \begin{macrocode}
\everydisplay\expandafter{%
  \the\everydisplay
  \def\baselinestretch{1.2}\selectfont}
%    \end{macrocode}
% Finally, we adjust to skip amounts to reflect the increased line spacing.
%    \begin{macrocode}
\smallskipamount=2pt plus 1.5pt minus 1.5pt
\smallskipamount=4pt plus 3pt minus 3pt
\bigskipamount=8pt plus 6pt minus 6pt
%    \end{macrocode}
% \section{Margins}
%
% We simplify matters by using the \package{geometry}. The GSAS
% guidelines calls for letter paper ($8 \times 11.5$ inch) and the
% margins given in the table on p.~\pageref{tbl:margins}.
% Furthermore, the guidelines call for the top margin of the first
% page of each chapter to be at least 2in.  The latter is more than
% provided for by the \package{book} class which hard codes a 50pt
% vertical space on top of the chapter heading.
%    \begin{macrocode}
\RequirePackage[letterpaper]{geometry}
\ifbd@minmar

% \begin{macro}{\bd@signline}
%   \mcmd{\bd@signline}\marg{witdh} produces a line of width \meta{width} for signatures.

% \begin{environment}{optionalpage*}
% \begin{environment}{optionalpage}
%   These environments are used for optional pages: dedication,
%   acknowledgments, preface.  They take \meta{title} as their single
%   argument. 
%
%   The unstarred version adds an entry to
%   the table of contents.

%   We do not use \cmd{\chapter}\ostar as
%   this has a large space on the top of the page.
%   The output will be double-spaced, but you can easily change that.
