% This is the file satmacros.tex, for use with Surveys in Approximation Theory.
% It contains the definition of the various macros that appear in the
% template file  textemplate.tex , along with macros that support them.
% In addition, it contains macros you might find useful (along with their
% supporting macros).
%
% If you choose to change anything in this file, be sure to give it a
% different name first.

% The file is organized in sections.
% Each section with a title in CAPITALS begins with the macros you would
% actually be using (in additions to those that appear in the template file
% textemplate.tex), followed by supporting macros.
% The other sections only contain macros mentioned in textemplate.tex and
% supporting macros.
