%% - Added support for references by author name(s) and date of publication 
%%   (via the alphacitations package option)
%% - Added compliant option to make this package follow the published formatting
%%   guidelines as closely as possible
%% - Added compliantmargins option to force pages to always be numbered in the 
%%   upper-right corner (and remove all other text from the page margin)
%% - Figures and tables automatically centered (with top, bottom, and here) as 
%%   default placement options
%% - Added copyright command to allow users to modify the copyright notice
%% - Added electronic and print options to automatically set options for final 
%%   versions of thesis
%% - Fixed (potential) bug where quotation environment had too much space before
%%   and after quoted text

%%   pages)
%% 1.2.46
%% - Changed definition of default placement of figures and tables (more 
%%   compliant with LaTeX's default) -- should NOT have visible changes

%% - Abstract and acknowledgments hidden when hidefront specified
%% - Removed "Compiled" from draft notice in footer
%% - Lightened draft watermark

%%   chapter name and mark and use this feature for the implementation of 
%%   acknowledgements environment
%% 1.2.54
%% - Corrected bug in setting line space for typewriterdoublespace option
%% - final option specified for microtype package so not disabled by draft
%%   class option
%% - Table of contents printed on back of title page with hidefront option

%% - Removed final option for microtype package
%% - Corrected bug causing extra page to appear after \listoffigures
%% =============================================================================

%% =============================================================================
%% TODO
%% =============================================================================
%% - Combine style and documentation into .dtx managed by Doc and DocStrip
%% - Integrate with svn-multi package for version identifiers (particularly of
%%   drafts)
%% - Create thesis skeleton (Makefile, paper.tex, chapters/*.tex, figs/, etc.) 
%%   to distribute as example
%%
%% - Signatures extend onto second page with 12pt and 6+ committee members 
%%   (thanks to Ross Gore)
%% - showlabels support added to draft option automatically
%% - print option should issue warning if twoside is active

% LaTeX is most uncooperative with regards to redefining the chapter command. 
% While it is possible to backport some hacks from the book class, a portable 
% (i.e., robust to different classes) solution appears out of reach.
%
% The fancyhdr package may provide an alternate workaround, but here we redefine
% the plain page style (ps@plain) as the myheadings page style (ps@myheadings). 
% Hence, when LaTeX calls \thispagestyle(plain) at the start of parts, chapters,
% etc., the myheadings page style will actually be used.
\if@uvaseasthesis@compliantmargins
  \let\ps@plain=\ps@myheadings\relax
