% Version history
%  v0.3: - Fixed some errors in the documentation
%        - Colors specified in \shadowcolor should now be specified using 
%          color names, not RGB values. The command for specifying colors 
%          using RGB values has been renamed to \shadowrgb. 
%          (I apologize for the backwards incompatibility).
%        - The base line of the text is now correct.
