% \section{Introduction}
%
% This package defines a \LaTeX\ thesis class for Drexel University
% conforming to the
% \href{http://www.library.drexel.edu/files/services_documents/thesismanual.pdf}
%   {Drexel University Thesis Manual version 2009/06/01}.
%
% \section{Usage}
%
% To write a thesis, you load the Drexel thesis definitions by loading
% the \pkg{drexel-thesis} class at the beginning of your
% \LaTeX\ document with the |\documentclass| command.  For example,
% \begin{example}
%   \documentclass{drexel-thesis}
% \end{example}
%
% \subsection{Options}
%
% \DescribeOptions{final,draft}
% The default option (selected if not options are passed) is
% \Lopt{final} mode, which has all the proper formatting and spacing
% for your final product. The other main option is \Lopt{draft} mode,
% which reduces all the spacing in the document, so might be helpful
% when printing out drafts (saves paper).
%
% \Lopt{final} mode corresponds to (with Thesis Manual chapter and
% verse) \\
% \begin{tabular}{r p{0.8\textwidth}}
%   \Lopt{oneside} & 1.5 Library Submission Information, Print
%     Version: ``All copies must be: \ldots Typed/printed on only one
%     side of the page (not double-sided).'' \\
%   \Lopt{finalspace} & Assorted single, double, and triple spacing
%   directives. \\
%   \Lopt{dottedtoc} & From the example on p17.
% \end{tabular}
%
% \Lopt{draft} mode corresponds to \\
% \begin{tabular}{r p{0.8\textwidth}}
%   \Lopt{twoside} & Save space. \\
%   \Lopt{draftspace} & Save space. \\
%   \Lopt{dottedtoc} & Might as well be consistent with \Lopt{final}. \\
%   \Lopt{draftwatermark} & It's good to have a timestamp. \\
% \end{tabular}
%
% \DescribeOption{finalspace}
% Loosen spacing.
%
% \DescribeOption{draftspace}
% Tighten spacing.
%
% \DescribeOptions{dottedtoc,boldtoc,
%                  dottedpart,boldpart,
%                  dottedchapter,boldchapter}
% These options change how the relevant TOC lines are printed
% \LaTeX\ defaults to bold but not dots.  The \Lopt{*toc} options set
% all of the types.  For example, \Lopt{boldtoc} is equivalent to
% \Lopt{boldchapter,boldpart}.
%
% \DescribeOption{draftwatermark}
% \Lopt{draftwatermark} adds ``DRAFT \meta{date}'' watermarks to each
% page.  A useful way to remember that the version you're looking at
% is not final.  Also helps reviewers tell you what version they're
% correcting.
%
% \DescribeOption{indentfirst}
% \Lopt{indentfirst} indents the first paragraph after sections etc.
%
%
% \subsubsection{Interesting \cls{book} options}
% 
% \DescribeOption{oneside}
% Setup output for one-sided printing.
%
% \DescribeOption{twoside}
% Setup output for two-sided printing.
%
% \DescribeOption{leqno}
% \Lopt{leqno} places the numbering of formulae on the left hand side
% instead of the right.
%
% \DescribeOption{fleqn}
% \Lopt{fleqn} typesets displayed formulae left-aligned instead of
% centered.
%
%
% \subsection{Macros}
%
% \begin{command}
%   `\cs{author}\marg{name}'
% \end{command}
% \DescribeMacro{\author}
% Use this macro to set your full name to \meta{name}, including
% your middle initial or name.  For example
% \begin{example}
%   \name{Richard P. Feynman}
% \end{example}
% See the Manual 3.1 p8.
%
% \begin{command}
%   `\cs{title}\marg{title}'
% \end{command}
% \DescribeMacro{\title}
% Use this macro to set your thesis title to \meta{name}.  For example
% \begin{example}
%   \title{A New Approach to Quantum Theory}
% \end{example}
% See the Manual p16.
%
% \begin{command}
%   `\cs{advisor}\marg{name}'
% \end{command}
% \DescribeMacro{\advisor}
% Use this macro to set your advisor's name to \meta{name}.  For
% example
% \begin{example}
%   \advisor{John A. Wheeler, Ph.D.}
% \end{example}
% You can set multiple advisors, if appropriate, by calling |\advisor|
% multiple times.
% \begin{example}
%   \advisor{John A. Wheeler, Ph.D.}
%   \advisor{Advisor 2}
% \end{example}
% See the Manual 3.1 p8.
%
% \begin{command}
%   `\cs{defmonth}\marg{month}'
%   `\cs{defyear}\marg{year}'
% \end{command}
% \DescribeMacro{\defmonth}
% \DescribeMacro{\defyear}
% Use these macros to set the month with \meta{month} (spelled out)
% and year with \meta{year} (four digits) of your thesis defense.  For
% example
% \begin{example}
%   \defmonth{June}
%   \defyear{1942}
% \end{example}
% See the Manual 3.1 p8.
% The |def| in |\def*| avoids collisions with the plain \TeX\ 
% |\month| and |\year| (see the
% \href{http://www.tug.org/utilities/plain/cseq.html#month-rp}{month}
% and
% \href{http://www.tug.org/utilities/plain/cseq.html#year-rp}{year}
% entries in the HTML version of David Bausum's \emph{TeX Reference
% Manual}).
%
% \begin{command}
%   `\cs{degree}\marg{degree}'
% \end{command}
% \DescribeMacro{\degree}
% Set your target degree with \meta{degree}.  From the Manual 3.1 p8.
% \begin{quote}
%   Write out the name of the degree for which you are a candidate.
%   All Ph.D.\ candidates must use |Doctor of Philosophy|.  All
%   Master's degree candidates should use the precise degree name
%   (e.g., |Master of Science in Mechanical Engineering|).
% \end{quote}
% So, for a Ph.D candidate,
% \begin{example}
%   \degree{Doctor of Philosophy}
% \end{example}
%
% \begin{command}
%   `\cs{copyrighttext}\marg{text}'
% \end{command}
% \DescribeMacro{\copyrighttext}
% Use this macro to set the copyright text to \meta{text}.
% The default value is ``All Rights Reserved.''.
% \begin{example}
%   \copyrighttext{Released to the Public Domain.}
% \end{example}
% See the Manual 3.2 p9.
%
% \begin{command}
%   `\cs{copyrighttextCC}'
% \end{command}
% There are a number of predefined copyright messages for ease of use \\
% \begin{tabular}{l l}
%   |\copyrighttextCC| & Creative Commons copyright \\
% \end{tabular}
%
% \begin{command}
%   `\cs{tableofcontents}'
% \end{command}
% \DescribeMacro{\tableofcontents}
% Write the table of contents (Manual 3.5 p9).  You can control the
% verbosity by setting |\tocdepth| according to the following table
% (\href{http://www.image.ufl.edu/help/latex/intext.shtml}{source}). \\
% \begin{tabular}{l l l}
%   Depth in document & Section Command & Depth for |\secnumdepth| Command \\
%   -1 & |\part| & 1 \\
%    0 & |\chapter| & 2 \\
%    1 & |\section| & 3 \\
%    2 & |\subsection| & 4 \\
%    3 & |\subsubsection| & 5 \\
%    4 & |\paragraph| & 6 \\
%    5 & |\subparagraph| & 7
% \end{tabular} \\
% For example, to expose everything down to and including the
% |\subsection| level, you would add
% \begin{example}
%   \setcounter{tocdepth}{2}
% \end{example}
% to your preamble (the section before |\begin{document}|, not the
% |preamble| environment discussed below).
%
% Note that the Manual 3.5 p9 requires ``List chapter titles and at
% least the first and second order subdivisions.'', which corresponds
% to a |\tocdepth| of at least 2.
%
% \begin{command}
%   `\cs{listoftables}'
% \end{command}
% \DescribeMacro{\listoftables}
% Write the List of Tables page (Manual 3.7 p10).
% Skip if you have no tables in your thesis.
%
% \begin{command}
%   `\cs{listoffigures}'
% \end{command}
% \DescribeMacro{\listoffigures}
% Write the List of Figures page (Manual 3.7 p10).
% Skip if you have no figures in your thesis.
%
% \begin{command}
%   `\cs{blanklines}\marg{num}'
% \end{command}
% \DescribeMacro{\blanklines}
% Insert \meta{num} blank lines.  For example
% \begin{example}
%   \blanklines{2}
% \end{example}
% The skipped lines are always \emph{single spaced} lines, regardless
% of the current line spacing in the environment calling this macro.
%
%
% \subsection{Environments}
%
% \DescribeEnv{preamble}
% Generalize the |\frontmatter| for the thesis, setting up page
% numbering, including the title page, copyright page etc.  The
% |preamble| environment should contain the following elements
% (in order, see the Manual p8)
% \begin{itemize}
%   \item |dedication| environment (optional)
%   \item |acknowledgments| environment (optional)
%   \item |\tableofcontents|
%   \item |\listoftables|
%   \item |\listoffigures|
%   \item |abstract| environment
% \end{itemize}
% This will take care of everything from the title page (Manual 3.1),
% up through the blank page before the text (Manual 3.9).
%
% \DescribeEnv{dedications}
% Set the dedications text.
% Highlights from the Manual 3.3 p9:
% \begin{quote}
%   The |Dedications| page is optional.
% \end{quote}
%
% \DescribeEnv{acknowledgments}
% Set the acknowledgments text.
% Highlights from the Manual 3.4 p9:
% \begin{quote}
%   The |Acknowledgments| page is optional, but most theses do
%   include a brief statement of thanks or recognition of any special
%   assistance.
% \end{quote}
%
% \DescribeEnv{abstract}
% Set the thesis abstract text.  In the Thesis Manual, see section 3.8
% Abstract (p10) for details, p20 for an example.
%
% Highlights from the Manual:
% \begin{quote}
%   The abstract is a summary that allows readers to determine the
%   value of reading the full thesis.  It should include a statement
%   of the problem, an outline of procedures or methods, and a summary
%   of results and conclusions.
% \end{quote}
% \begin{itemize}
%   \item Word limits: 600 for a Master's thesis, 350 for a Ph.D.\ thesis.
% \end{itemize}
%
% \DescribeEnv{thesis}
% Set the thesis text.  In the Thesis Manual, see section 3.10 Thesis
% (p11) for details.
%
% Highlights from the Manual:
% \begin{quote}
%   Divide the text into its major parts/chapters/subsections.  No
%   fixed arrangement is necessary.  The major parts may contain such
%   subjects as introduction, general argument, description of
%   experimental procedures, research methods, discussion, summary,
%   conclusions, recommendations, and other pertinent topics that are
%   necessary for a complete understanding on the part of a
%   sophisticated or professional reader.
% \end{quote}
%
% \DescribeEnv{vita}
% Set the thesis vita text (Ph.D.\ only).  See the Manual 3.15 p12,
% ``Vita'', for details.
%
% Highlights from the Manual:
% \begin{quote}
%   The Vita is a biography of the student written in the third person
%   in either essay or outline form.  It should include the full name,
%   place and date of birth (optional), country of citizenship
%   (optional), institutions attended, degrees and honors received,
%   titles of publications, teaching and professional experience, and
%   other pertinent data.  The Vita must be one page or less.
% \end{quote}
%
%
% \subsection{Hints}
%
%
% \subsubsection{Package installation}
% \label{sec:dependencies}
%
% All the packages this class depends on must be installed somewhere
% in your texmf tree (they probably already are).  If not, you will
% recieve warning messages on compilation such as
% \begin{example}
%   ! LaTeX Error: File `missing-package.sty' not found.
% \end{example}
% You should then install the missing package(s) using your operating
% systems package manager, or grab the missing package from
% \href{http://www.ctan.org/}{CTAN}, and install them following TODO.
%
%
% \subsubsection{Tables and Figures}
%
% From the Manual 2.3 p6, ``Tables and Figures'', 
% \begin{quote}
%   Place figure captions below figures.
%   Place table captions above tables.
% \end{quote}
% so make sure the |\caption| command is in the appropriate location.
% For example
% \begin{example}
%   \begin{table}
%      \caption{Some caption text}
%      \begin{tabular}{...}
%        ...
%      \end{tabular}
%   \end{table}
% \end{example}
% or
% \begin{example}
%   \begin{float}
%      \includegraphics{...}
%      \caption{Some caption text}
%   \end{float}
% \end{example}
% \pkg{drexel-thesis} loads
% \href{http://www.ctan.org/tex-archive/macros/latex/required/graphics/}{\pkg{graphicx}}
% to define the |\includegraphics| macro.  For more useful
% float information, see the
% \href{http://en.wikibooks.org/wiki/LaTeX/Floats,_Figures_and_Captions}
%   {\LaTeX\ wikibook page}.
% 
%
% \subsubsection{Citations}
%
% I highly recommend using \BibTeX\ and
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/natbib/}{\pkg{natbib}}.
% See Section \ref{sec:better-example} for a simple example.
%
% Suggested options:\\
% \begin{tabular}{r p{0.8\textwidth}}
%   |super| & selects citations in superscript mode. \\
%   |sort&compress| & automatically sorts and compresses compound
%     citations (|\pcite{a,b,...}|).
% \end{tabular}
%
%
% \subsubsection{References}
%
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/cleveref/}{\pkg{cleveref}}.
% Is a wonderful tool for easy, consistent crosslinking.  The manual is also very good.
%
%
% \subsubsection{Hyperlinks}
%
% \cls{drexel-thesis} loads
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/hyperref/}{\pkg{hyperref}}.
% with the options:\\
% \begin{tabular}{r p{0.8\textwidth}}
%   |colorlinks| & color the link letters instead of drawing colored boxes. \\
% \end{tabular}
%
% If running with a pdftex-based driver, |\author|, |\title|, and
% |\degree| automatically set |pdfauthor|, |pdftitle|, and
% |pdfsubject| respectively.  You can use the |\hypersetup| macro to
% set options overriding these defaults.

% \subsection{Internal package includes}
%
%
% Include some other packages we'll need.  If the package is not
% installed on your system, see Section \ref{sec:dependencies} for
% installation instructions.
%
% For many packages, we want the same functionality for both
% \Lopt{final} and \Lopt{draft} modes.  We pass \Lopt{final} to most
% of those packages to override a possible \Lopt{draft} option passed
% to \pkg{drexel-thesis}.
%
%
% \subsubsection{\pkg{setspace}}
%
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/setspace/}{\pkg{setspace}}
% for double spacing.
%    \begin{macrocode}
\RequirePackage{setspace}
%    \end{macrocode}
%
%
% \subsubsection{\pkg{calc}}
%
% \href{http://www.ctan.org/tex-archive/macros/latex/required/tools/}{\pkg{calc}}
% for |\blanklines| macro.
%    \begin{macrocode}
\RequirePackage{calc}
%    \end{macrocode}
%
%
% \subsubsection{\pkg{graphicx}}
%
% \href{http://www.ctan.org/tex-archive/macros/latex/required/graphics/}{\pkg{graphicx}}
% for |\includegraphics|.  Not strictly necessary, but I can't imagine
% a thesis without figures.
%    \begin{macrocode}
\RequirePackage[final]{graphicx}
%    \end{macrocode}
%
% We include the graphicx package now so we can
% pass \Lopt{final}, because some later packages include it with no options,
% and a \Lopt{final} include after that produces errors like
% \begin{example}
%   l.104 \RequirePackage
%                        [final]{ifpdf}
%   The package graphicx has already been loaded with options:
%     []
%   There has now been an attempt to load it with options
%     [final]
% \end{example}
%
%
% \subsubsection{\pkg{draftmark}}
%
% The Comp.~Sci.\ class used
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/draftcopy/}{\pkg{draftcopy}}
% to add their watermarks, but as of the current 2002/02/25 v2.16, it
% uses postscript specials, and so doesn't work with pdf\LaTeX.
% Instead we use the recent (catalogued 2009/11/03)
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/draftmark/}{\pkg{draftmark}}
% which unfortunately has a number of apparently non-standard dependencies
% (\href{http://www.ctan.org/tex-archive/macros/latex/contrib/etextools/}{\pkg{etextools}},
%  \href{http://www.ctan.org/tex-archive/macros/latex/contrib/etoolbox/}{\pkg{etoolbox}},
%  \href{http://www.ctan.org/tex-archive/macros/latex/contrib/lastpage/}{\pkg{lastpage}},

%  \href{http://www.ctan.org/tex-archive/macros/latex/contrib/xifthen/}{\pkg{xifthen}},
%  if only I had the space to install |texlive-latexextra| |:p|).
% The output is, however, very flexible, and it \emph{does} work with
% both \LaTeX\ and pdf\LaTeX.  If you don't like the default watermark,
% you can also adjust the particulars with |\draftmarksetup|.
%    \begin{macrocode}
\if@draftwatermark
  \RequirePackage[draft,allpages,mark={DRAFT \today},
                  fontsize=2cm,grayness=0.9]{draftmark}

%
%
% \subsubsection{\pkg{geometry}}
%
% Setup page margins with the
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/geometry/}{\pkg{geometry}}
% package.  From the Manual p5:
% \begin{itemize}
%   \item The left margin must be at least 1 1/2'' (1.5 inches)
%   throughout the document.
%   \item All other margins (top, bottom, and right) must be at least 1''.
% \end{itemize}
% And from the Manual 1.5 p4, Print Version:
% \begin{quote}
%   The paper size must be 8 1/2'' x 11''.
% \end{quote}
%    \begin{macrocode}
\RequirePackage[letterpaper,margin=1in,bindingoffset=0.5in]{geometry}
%    \end{macrocode}
% Note that we include the \pkg{geometry} package after loading \cls{book} to
% override the margin manipulation that takes place in \cls{book}.
%
%
% \subsubsection{\pkg{fancyhdr}}
%
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/fancyhdr/}{\pkg{fancyhdr}}
% for correct page numbering and fancy headers.
% From the Manual 2.3 p5, ``Pagination''
% \begin{quote}
%   Place page numbers in the upper right-hand corner of the page,
%   3/4'' from the top.
% \end{quote}
%    \begin{macrocode}
\RequirePackage{fancyhdr}
%    \end{macrocode}
% Setup the standard |fancy| format.
%    \begin{macrocode}
\pagestyle{fancy}
\fancyhf{}
\renewcommand{\headrulewidth}{0pt}
%    \end{macrocode}
% 0.4 pt is \pkg{fancyhdr}'s default |\headrulewidth|, so we'll
% recycle the value.
%    \begin{macrocode}
\renewcommand{\footrulewidth}{0.4pt}
%    \end{macrocode}
% |\leftmark| is the higher level mark, see |\chaptermark| below.
% |\rightmark| is the lower level mark, see |\sectionmark| below.
% We put the lower level mark to the outside because it changes more
% often.  Page numbers also go on the outside.
%    \begin{macrocode}
\fancyfoot[RE,LO]{\slshape\leftmark}
\fancyfoot[LE,RO]{\slshape\rightmark}
\fancyhead[LE,RO]{\thepage}
%    \end{macrocode}
% Override the |plain| format (for part pages, etc.).
%    \begin{macrocode}
\fancypagestyle{plain}{
  \fancyhf{}
  \renewcommand{\footrulewidth}{0pt}
  \fancyhead[LE,RO]{\thepage}

%    \end{macrocode}
% Keep the |empty| format at its default.
%    \begin{macrocode}
\fancypagestyle{empty}{
  \fancyhf{}
  \renewcommand{\footrulewidth}{0pt}
}
%    \end{macrocode}
%
%
% \subsubsection{\pkg{ifpdf}}
%
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/oberdiek/}{\pkg{ifpdf}}
% for detecting PDF drivers.  We use it to configure \pkg{hyperref} below.
%    \begin{macrocode}
\RequirePackage{ifpdf}
%    \end{macrocode}
% 
% \subsubsection{\pkg{hyperref}}
%
% \href{http://www.ctan.org/tex-archive/macros/latex/contrib/hyperref/}{\pkg{hyperref}}
% for hyperlinks.  Not strictly necessary, but I can't imagine a
% thesis without it.
%    \begin{macrocode}
\RequirePackage[final]{hyperref}
%    \end{macrocode}
% Nobody likes the default colored boxes.  Color the text itself.
%    \begin{macrocode}
\hypersetup{colorlinks}
%    \end{macrocode}
% If we're writing a PDF, we set the |pdfauthor|, etc.\ arguments in
% |\author|, etc.\ to avoid using |\AtBeginDocument| or some such.
%
%
% \subsection{\LaTeX\ overrides and extensions}
%
% Here we change the behavior of a bunch of macros and environments
% from \file{latex.ltx} (generated by \file{format.ins} in
% \href{http://www.ctan.org/tex-archive/macros/latex/base/}{\pkg{base}}).
% We'll copy in their original notes along with their code, following
% the relevant documentation an order given in \file{format.ins} and
% the associated \file{*.dtx} files.
%
%

% The \BibTeX\ program will create a file containing such an
% environment, which will be read in by the |\bibliography| command.
% With \BibTeX, the following commands will be used.
%
% The document class must define the thebibliography environment.  This
% environment has a single argument, which is the widest bibliography
% label-- e.g., if the [Knuth67] is the widest entry, then this

% \subsubsection{Appendix}
%
% \begin{macro}{\appendix}
% The |\appendix| command is not really an environment, it is a
% macro that makes some changes in the way things are done.
%
% In the article document class the |\appendix| command must do the
% following:
% \begin{itemize}
%   \item reset the section and subsection counters to zero,
%   \item redefine |\thesection| to produce alphabetic appendix
%         numbers. This redefinition is done globally to ensure that it 
%         survives even if |\appendix| is issued within an environment such
%         as \texttt{multicols}.
% \end{itemize}
%
% In addition to \cls{book}'s (or \pkg{hyperref}'s) activity, we add
% |\@appendixtrue|.  This gets |\if@appendix| working in our
% |\chapter| definition (Sec.~\ref{sec:implement-chapters}).
% (\file{classes.dtx}, L3177)
%    \begin{macrocode}
\let\DUT@appendix\appendix

% To help symmetrize the spacing around tables and figures, we set

% code comes in Section \ref{sec:implement-captions}.
% (\file{classes.dtx}, L3491)

%
% \subsubsection{Captions}
% \label{sec:implement-captions}
%
% \begin{macro}{\@makecaption}
% The |\caption| command calls |\@makecaption| to format the
% caption of floating objects. It gets two arguments,
% \meta{number}, the number of the floating object and \meta{text},
% the text of the caption. Usually \meta{number} contains a string
% such as ``Figure 3.2''. The macro can assume it is called inside a
% |\parbox| of right width, with |\normalsize|.
%
% We override \cls{book}'s |\@makecaption|, adding two |\if@table|
% conditionals, which swap |\abovecaptionskip| and |\belowcaptionskip|
% for tables (where the caption is above the float body).  With our
% implementation, |\belowcaptionskip| \emph{always} gives the distance
% between the caption and the text, and |\abovecaptionskip|
% \emph{always} gives the distance between the caption and the float
% body.  See Section \ref{sec:implement-tables} for our |\if@table|
% control.
%
% We also replace the caption lead-in |#1: #2| with
% |\small{\bfseries#1:} #2|.
% (\file{classes.dtx}, L3508)
%    \begin{macrocode}
%    \end{macrocode}
% Define a temporary length for swapping.
%    \begin{macrocode}
\newlength\@tempcapskip
%    \end{macrocode}
% The definition of this macro is |\long| in order to allow more
% then one paragraph in a caption.

%    \end{macrocode}
% We want to see if the caption fits on one line on the page,
% therefore we first typeset it in a temporary box.
%    \begin{macrocode}
  \sbox\@tempboxa{\small{\bfseries#1:} #2}%
%    \end{macrocode}
% We can the measure its width. It that is larger than the current
% |\hsize| we typeset the caption as an ordinary paragraph.
%    \begin{macrocode}
  \ifdim \wd\@tempboxa >\hsize
    {\small{\bfseries#1:} #2\par}
  \else
%    \end{macrocode}
% If the caption fits, we center it. Because this uses an |\hbox|
% directly in vertical mode, it does not execute the |\everypar|
% tokens; the only thing that could be needed here is resetting the
% `minipage flag' so we do this explicitly.

%
% \begin{macro}{\abovecaptionskip}
% \begin{macro}{\belowcaptionskip}
% For \cls{book}, these lengths contain the amount of white space to
% leave above and below the caption.  However, because of our work
% with |\@makecaption| (above), |\belowcaptionskip| \emph{always}
% gives the distance between the caption and the text, and
% |\abovecaptionskip| \emph{always} gives the distance between the
% caption and the float.

% \end{itemize}
% We inhibit the paging in draft mode and drop the \Lopt{twocolumn} code.

% \subsection{Caveats and bugs}
%
%
% \subsubsection{\pkg{hyperref} and uppercase}
%
% In order to comply with the Manual's specifications,
% part and chapter entries to the table of contents need
% to be uppercased, which we do via |\AddContentsLine|.
% This generates some whining from \pkg{hyperref}
% \begin{example}
%   Package hyperref Warning: Token not allowed in a PDF string (PDFDocEncoding),
%   (hyperref)                removing `\uppercase' on input line 72.
% \end{example}
% This is because |\uppercase| is parsed in \TeX's stomach, but
% \pkg{hyperref} deals with code in \TeX's mouth, so \pkg{hyperref} is
% drops the token and complains.  Which is fine, since the titles
% don't actually need to be uppercased in the bookmark, but the
% error messages are still produced.  If anyone knows of a good way
% to either fix the problem or silence these particular error messages,
% please let me know.  Otherwise, just ignore the errors.
