%  outlined by the GSAS for acceptable dissertation format.  Be sure to
%  check that the output matches the current specifications.  The
%  formatting requirements are on-line at:

%  under ``Dissertation Guidelines.''

%  This class was written using the guidelines in the ``LaTeX2e for

%**************************** Class Options  ************************

%  uncompressed|compressed -> compressed or uncompressed [default] PDF.
%  The uncompressed|compressed option is only meaningful when a PDF is
%  being produced.  If ``uncompressed'' is true, the PDF compression
%  level is set to 0 just before document production begins.  And so
%  ``compressed'' really means ``not uncompressed''.
\newif\if@uncompressed
\DeclareOption{uncompressed}{\@uncompressedtrue}
\DeclareOption{compressed}{\@uncompressedfalse}

%  online|printed -> online or printed [default] submission.
%  Pass these options to the brandiss package.
\DeclareOption{online}{\PassOptionsToPackage{\CurrentOption}{brandiss}}
\DeclareOption{printed}{\PassOptionsToPackage{\CurrentOption}{brandiss}}

%  Default Option: Pass all other options to the amsbook class.
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{amsbook}}

%  Default Setup:
%  Use uncompressed option by default.
\ExecuteOptions{uncompressed}

% GSAS formatting requirements: 12 point font and one-sided printing.
% Set up the amsbook class with these default options before option
% processing so they can be overridden by the passed options.
\PassOptionsToClass{12pt,oneside}{amsbook}

% Process the options.
\ProcessOptions\relax

%********************** Class and Package Loads  *****************

% The amsbook class provides the main document style.
\LoadClass{amsbook}

% Package brandiss provides front page commands.
\RequirePackage{brandiss}[2004/05/05 v1.0 Standard LaTeX package]

% Package ifpdf provides the \ifpdf command.
\RequirePackage{ifpdf}

% Package setspace provides line spacing command.
\RequirePackage{setspace}

% Package geometry sets the margins.  
% REQUIRED: Load before package fancyhdr.
\RequirePackage{geometry}

% Package fancyhdr allows us to set headers and footers.
\RequirePackage{fancyhdr}

%*********************** Settings and Definitions  ******************

% GSAS formatting requirements: If a PDF document is produced, it
% should not be compressed.
\ifpdf\if@uncompressed\AtBeginDocument{\pdfcompresslevel=0}\fi\fi

% GSAS formatting requirements: The left margin is a minimum of 1.5in.
% The top, bottom, and right margins are a minimum of 1in, except top
% margin of a chapter page is a minimum of 2in.  All printed matter
% fits in these margins.  We set the margings at the GSAS minimum.
% The margins of the first page of a chapter come from the amsbook
% format.
\geometry{
  left=1.5in, right=1in, top=1in, bottom=1in,%% The margins.
  includeheadfoot,%% Header and footer within the margins.
  headheight=3ex,%% Make the headers larger than text and
  headsep=30pt%% separate them from the main text.
}

% GSAS formatting requirements: The page number is consistently placed
% on every page except for the title, signature, and copyright pages.
% It may be centered at the bottom of every page.  We use the fancy
% page style for the main body of the document.  Since the plain style
% used for the front pages, back pages, and the first page of a
% chapter has the page number centered in the footer, we use that
% style for all pages by the least effort principle.
\pagestyle{fancy}
\renewcommand{\headrulewidth}{0.25pt} %% Thin header line.
\fancyhf{}                            %% Clear all fields.
\fancyfoot[C]{\tiny\thepage}          %% Centered page number in the footer.
\if@twoside
  \fancyhead[LE]{\small\leftmark}     %% Chapter name in the left header.
  \fancyhead[RO]{\small\rightmark}    %% Section name in the right header.
\else
  \fancyhead[L]{\small\leftmark}      %% Chapter name in the left header.
\fi

% GSAS formatting requirements: Double line spacing for the front and
% main parts of the document, and the front pages have roman
% numbering.  The \frontmatter command sets double line spacing for
% the whole document.  It also sets roman page numbering and plain
% page style for the pages at the front of the dissertation.
\renewcommand{\frontmatter}{%
  \doublespacing
  \cleardoublepage
  \pagenumbering{roman}
  \pagestyle{plain}
}

% GSAS formatting requirements: The main and back pages have arabic
% numbering.  The \mainmatter command sets arabic page numbering and
% fancy page style for the pages in the main part of the dissertation.
\renewcommand{\mainmatter}{%
  \cleardoublepage
  \pagenumbering{arabic}
  \pagestyle{fancy}
}

% The \backmatter command sets plain page style for the pages at the
% back of the dissertation (bibliography, index).
\renewcommand{\backmatter}{%
  \if@openright\cleardoublepage\else\clearpage\fi
  \pagestyle{plain}
