%% drafts.sty -- Release: Sept. 3, 1992
%% Author: H. Saiedian, U. of Nebraska at Omaha, hossein@unocss.unomaha.edu
%% (Initialization modified by rags 7 October 1992)
%% Usage:
%%          \documentstyle[...,drafts,...]
%%          ...
%%          \pagestyle{drafts}
%%
%% This style puts the word |DRAFT| on the top and bottom of each page and
%% then surrounds it with horizontal rule on both sides. Also date and
%% time of when the drafts were printed are shown on the bottom of each
%% each.
%%
%% A slightly-modified version of fancyheading.sty is used. drafts.sty has
%% three parts: fancyheadings stuff developed by Piet van Oostrum (Dept
%% of Computer Science, University of Utrecht, The Netherlands), TeX code
%% for getting the time, and the initializations. The initialization part
%% at the end allows for customization.
