%%---------------------------- Formatting Options ----------------------------%%
%%----------------------------------------------------------------------------%%
%%
%% -------------------------------------------------------------------------- %%
%% Disposition format -- any titles, headings, section titles
%% These formatting commands affect all headings, titles, headings,
%% so sizing commands should not be used here.
%% Formatting options to consider are
%% + \sffamily - sans serif fonts. Dispositions are often typeset in
%% sans serif, so this is a good option.
%% + \rmfamily - serif fonts
%% + \bfseries - bold face
%\dispositionformat{\sffamily\bfseries} % bold and sans serif
\dispositionformat{\bfseries} % bold and serif
%% -------------------------------------------------------------------------- %%
%% Formatting for centered headings - Abstract, Dedication, etc. headings
%% This is where one might put a sizing command.
%% \MakeUppercase can be used to typeset all headings in uppercase.
\headingformat{\large\MakeUppercase} % All letters uppercase
%\headingformat{\large} % Not all uppercase
%\headingformat{\Large\scshape} % Small Caps, used with serif fonts.
%% Typographers recommend using a normal inter-word space after
%% sentences. TeX's default is to add an wider space, but \frenchspacing
%% gives a normal spacing. Comment out the following line if you prefer wider spaces between sentences.
\frenchspacing
%% -------------------------------------------------------------------------- %%

%% A number of compatible packages to improve the look and feel of
%% your document are available in the file optional.tex
