%% USAGE:  \documentclass{ut-thesis}
%%         \documentclass[...options...]{ut-thesis}
%%
%% The default settings produce a final copy, ready for submission to
%% the School of Graduate Studies (SGS) at the University of Toronto:
%% single-sided, "normal" margins (see below), one-and-a-half spaced
%% with single-spaced notes.
%%
%% OPTIONS:
%%
%%  - Any standard option for the LaTeX2e `report' class, including
%%    `10pt', `11pt', `12pt', `oneside', `twoside', etc.
%%
%%  - `narrowmargins', `normalmargins', `widemargins', or
%%    `extrawidemargins':  Set the size of the margins, as follows:
%%     . `narrow': 1 1/4" on the left, 3/4" on all other sides,
%%       headers & footers 3/8" from body
%%       (these are the minimum values required by SGS);
%%     . `normal': 1 1/4" on the left, 1" on all other sides,
%%       headers & footers 1/2" from body;
%%     . `wide': 1 1/4" on all sides,
%%       headers & footers 5/8" from body;
%%     . `extrawide': 1 1/2" on all sides,
%%       headers & footers 3/4" from body.
%%    If you have more than just a few marginal notes, it is recommended
%%    that you use at least `wide' margins.  For other settings, use the
%%    \geometry command (see the template for details).
%%
%%  - `singlespaced', `oneandahalfspaced', or `doublespaced':  Set the
%%    entire document's default line spacing (except for notes, which
%%    are single-spaced by default).  For other settings, use the
%%    \setstretch command (see the template for details).
%%
%%  - `singlespacednotes' or `standardspacednotes':  Set line spacing
%%    for footnotes and marginal notes: either single-spaced or the same
%%    as the rest of the document.
%%
%%  - `cleardoublepagestyleempty', `cleardoublepagestyleplain', or
%%    `cleardoublepagestylestandard':  Set the page style for all
%%    "cleared" pages (empty pages inserted in two-sided documents to
%%    put the next page on the right-hand side) to either `empty',
%%    `plain', or whatever style is in effect when the page is cleared
%%    (the default).
%%
%%  - `draft':  Produce a draft copy (double-sided, double-spaced,
%%    normal margins, with the word "DRAFT" printed at all four corners
%%    of every page).
%%
%% Note that these options can be used to override the default or draft
%% document settings, so that it is possible, for example, to create a
%% double-sided final copy, or a 1 1/2-spaced draft copy with wide
%% margins, etc.  You may use standard LaTeX packages to tailor the
%% layout and formatting in other ways.
%% Also note that when producing double-sided documents while _not_ in
%% draft mode, new chapters and preliminary sections will always start
%% on a right-hand page under the default settings (inserting a blank
%% page if needed).  This can be overridden by using the `openany' or
%% `openright' options.  To achieve this effect for individual sections
%% or chapters, use \cleardoublepage -- or one of the more specific
%% \clearemptydoublepage, \clearplaindoublepage, \clearthesisdoublepage,
%% or \clearstandarddoublepage (see below for details).
%%
%% NEW ENVIRONMENTS and COMMANDS:
%%
%%  * \degree{...}:  (preamble only; REQUIRED)
%%    Specify the name of the degree (e.g., "Doctor of Philosophy").
%%
%%  * \department{...}:  (preamble only; REQUIRED)
%%    Specify the name of the graduate department.
%%
%%  * \gradyear{...}:  (preamble only; REQUIRED)
%%    Specify the year of graduation (defaults to current year).
%%
%%  * \author{...}:  (preamble only; REQUIRED)
%%    Specify the name of the author.
%%
%%  * \title{...}:  (preamble only; REQUIRED)
%%    Specify the title of the thesis.
%%
%%  - \begin{preliminary}...\end{preliminary}:
%%    Delimit head matter (title page, abstract, table of contents,
%%    lists of tables and figures, etc.): set the page style and
%%    numbering for the preliminary sections and reset them for the main
%%    document.
%%
%%     - \maketitle:
%%       Generate the title page from the information supplied in the
%%       preamble.
%%
%%     - \begin{abstract}...\end{abstract}:
%%       Generate the abstract page, double-sided.  (According to SGS
%%       guidelines, this must immediately follow the title page.)
%%
%%     - \begin{dedication}...\end{dedication}:
%%       Generate a dedication section, if needed (just a paragraph
%%       formatted flush right).
%%
%%     - \begin{acknowledgements}...\end{acknowledgements}:
%%       Generate an acknowledgements section, if needed.
%%
%%    Note that neither the `dedication' nor the `acknowledgements' are
%%    put on a separate page by default (use \newpage to do this
%%    explicitly).  Also note that the table of contents, list of
%%    tables, and list of figures can be generated using the usual LaTeX
%%    commands.
%%
%%  - \begin{longquote}...\end{longquote}:
%%    Single-spaced version of the `quote' environment.
%%
%%  - \begin{longquotation}...\end{longquotation}:
%%    Single-spaced version of the `quotation' environment.
%%
%%  - \clearemptydoublepage, \clearplaindoublepage,
%%    \clearthesisdoublepage:
%%    Same as \cleardoublepage except that cleared pages have style
%%    `empty', `plain', or `thesis' respectively.
%%
%%  - \clearstandarddoublepage:
%%    Same as the original \cleardoublepage (cleared pages use the style
%%    currently in effect) -- used to override the effects of options
%%    `cleardoublepagestyleempty' or `cleardoublepagestyleplain'.
%%
%% The companion file `ut-thesis.tex' contains a skeleton illustrating
%% the use of this class.
