%  Needs AMSTEX 2.1 (incl. fonts)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%      Uses AMSTEX 2.1 and psbox package
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% 
% This collection of files was produced with CERN psbox package
% To decompose and tex it:
%-save this with a filename CONTAINING ONLY LETTERS and a .TEX
% extension (say, JOINTFIL.TEX), in some uncrowded directory;
%-make sure you can \input psbox.tex (version>=1.3);
% (else ftp cs.nyu.edu(=128.122.140.24):pub/TeX/psbox/, then get
% and tex the file psboxall.tex; more info in psbREAD.ME)
%-tex JOINTFIL.TEX using Plain, or LaTeX, or whatever is needed by
% the first file in the joining (after splitting JOINTFIL.TEX into
% it's constituents, TeX will try to process it as it stands).
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%       use amstex
%%%%%   
%%  If it is impossible for you to obtain psbox and/or you
%%  can not include
%%  Postscript figures, then you can also split this
%%  File by hand.  Besides the figures it contains
%%  only a file of private macros   called diffmac.tex
%%  just ignore all error messages related to the fidgures
%%                  Martin Schlichenmaier
%%  if all fails 
%%  make anonymous ftp to lie.math.uni-mannheim.de
%%  and obtain a postscript versions as file
%%  papers/diff.ps     or   request a hardcopy  
%%   e-mail: schlichenmaier at math.uni-mannheim.de
