%                           article, scrbook, etc classes in WWU style
% Version: 1.0 (03.03.2011) Small adjustments for publication. Colors
%                           are now globally defined and may be used in
%                           user code.

%                           in his document, the style does not get
%                           corrupted anymore.
%                           Added fontenc as requirement, some things
%                           look better with it.
%                           Removed institute from title page, looked too
%                           crowded.
% Version: 0.1 (13.02.2010) Initial version
%
% Usage:    Just put \usepackage{wwustyle} in the header of your tex
%           file, thats all!
%           You may reset the main color by using COLORCODE
%           as an option to the package, where COLORCODE is the
%           name of the color (in one word, all in small letters)
%           as defined in the corporate design manual which is
%           to be found on the web:
%           http://www.wwu.de/corporate-design/
%           Furthermore, if you choose the option "wide", you will get
%           presentations in 16:10.
% Remark:   This uses the MetaNormal font, which is to be found as
%           a latex font on the homepage of the WWU and should be available
%           for employees in the tex distribution on the WWU workstations.
