% A simple style file to provide a draft marking in the background of
% a file
% Thank you to Will Uther who provided the base code that I rolled
% into this package
% ChangeLog
% 1.1: shrunk and shifted the stamp so that it avoid the unprintable
% area at the top of the page
% 1.2 dkoes - made it big and rotated and light
% 1.3 dkoes - made it small, and unrotated since Jonathan Aldrich complained
% 1.4 comar - moved it below the page number to avoid problem with synctex
