%% dukedissertation -- a document class for dissertations and theses
%% conforming to the 2007 Duke University guidelines.  This class is by
%% Michael Gratton.  It is based on the 2004 LaTeX 2e version of 
%% report.cls and code in the older dukethesis.sty.
%%
%% report.cls is Copyright 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 
%% 2003 2004 The LaTeX3 Project.

%% Sean O'Connell, Michael Todd, Syam Gadde, and Rajiv Wickremesinghe.

%% Version 0.41
%% August 8, 2014  - Peter Hollender (peterhollender@gmail.com)
%% 		Just one tiny change: made title single-spaced on both the title 
%%		and abstract title pages.
%%
%% Version 0.40
%% October 27, 2008  - Michael Gratton (mgratton@math.duke.edu)
%% 
%% This class conforms to the 2007 style guidelines for dissertations,
%% including:
%% 1) Page numbers centered in the footer of each page
%% 2) Margins: 1in top, 1in right, 1.5in left, 1in below footer
%% 3) Title signature page, UMI abstract title signature page, and copyright 
%%    page automatically generated at \maketitle
%% 4) 'Double' spacing throughout body text (really about 10pt extra instead
%%    of 12pt extra, but it passes)
%% 5) Single spacing in the Table of Contents, List of Tables, List of 
%%    Figures, Bibliography, and in chapter, section titles, and figure/table 
%%    captions.
%% 6) Footnotes are numbered consecutively within a chapter and placed at the
%%    bottom of the page on which the reference number appears.
%% 7) Page ordering and numbering: roman numeral page numbers appear
%%    in the frontmatter (prior to the introduction or Chapter 1).  The first 
%%    numbered page is the Abstract (usuall iv).  Arabic numbering from '1'
%%    starts in the Introduction or Chapter 1 if there's no Introduction.
%% 8) Optional material supported: 
%%    *Dedication
%%    *Acknowledgements
%%    *Introduction (different from 'Chapter 1: Introduction')
%%    *Appendicies
%%
%% This class also provides some handy features:
%% 1) Use the option 'economy' to get a single-spaced document appropriate for
%%    giving to colleagues.
%% 2) Change your copyright from 'All rights reserved' if you're not actaully
%%    reserving all your rights.
%% 3) NEW LOOK: Boldface mostly removed in headers for a lighter feel.  
%%    The word 'Chapter' no longer appears on opener pages, only the number.
%% 4) OLD LOOK: there's now an option 'oldstyle' to get the standard LaTeX
%%    report.cls look back
%%
%% Limitations:
%% In it's current form, this class does not support committees larger than
%% six members or titles longer than four lines.  The 
%% figure-to-caption space has been abbreviated, as most plotting programs 
%% provide ample bottom margins.

%       DOUBLE    S P A C I N G:
% Most of the bother in the thesis format is in the disgusting double
% spacing requirements.  We handle it by a bit of plain TeX.  The 
% \openup command increases the space between baselines unscaled by font
% size.  Double-spacing is
% turned off by the macro \normalbaselines in figure captions, the toc,
% lof, lot, and bibliography.  In the later four, we FAKE double-spacing,
% typically with a \@SimSpace vertical space between entries.
