% THE NEXT LINES GIVE DEFINITIONS FOR THE THEOREM ENVIRONMENTS.
% EACH IS VIEWED AS A theorem environment IN THE SENSE OF LaTeX.
% THEIR NAMES ARE: Theorem, Proposition, Lemma, Corollary, Proposition,
% Criterion, Definition, Conjecture, Example, Problem, Remark, 
% Summary, and Acknowledgement.  ALSO INCLUDED WITHIN encs.sty ARE THE
% ENVIRONMENTS Note, Claim and Case UNDER THEIR OWN NAMES, AND THE
% ENVIRONMENT Algorithm UNDER THE NAME alg; FOR THIS USE 
% \begin{alg} text \end{alg}.
% TYPE \begin{name} text \end{name} AS USUAL FOR ENVIRONMENTS IN LaTeX.
% THE ENVIRONMENT name IS NUMBERED WITHIN section. E.G. THE FIRST 'Name' 
% IN SECTION 1 IS NUMBERED 'Name 1.1'
