%% This is the file thesis-gwu.cls.
%% It provides a LaTeX class that is consistent with the guidelines
%% provided by the School of Engineering and Science as described at
%%   <http://library.gwu.edu/node/1128>
%%
%% GWU provides a sad excuse for a LaTeX template and this is an attempt to 
%% improve.
%%
%% This class is based on the LaTeX template provided at
%%   <http://www-personal.umich.edu/~dalle/codes/thesis-umich/>
%%
%% The correct usage of this template is to use it as a documentclass.
%% The first line of the .tex file should be
%%
%%     \documentclass{thesis-gwu}
%%
%% if this file is in the same directory as the .tex file.  If the
%% two files are not in the same directory, the relative path from
%% the .tex file to this .cls file should be provided.  For example,
%% if the document is called thesis-dalle.tex and this file,
%% thesis-umich.cls is in a subfolder called 'tex', the command
%% should be
%%
%%     \documentclass{./tex/thesis-gwu}
%%
%% An example is distributed with this file that demonstrates all
%% of the features of the template.  The example is in a file called
%% thesis-sample.tex.
