% The go package stomps all over the LaTeX namespace.  Rather than
% individually rename each of the fairly few user-visible symbols that
% go provides, we provide this package to define only those symbols we
% care to typeset.

% The original package lacks the following two lines so we fabricate
% them ourselves from the header comments.
