% THE FOLLOWING implement \shortref, \longref, and \longrefs mentioned
% below. 
%
% An existing package exists on CTAN called refstyle that could be used
% to replace the following. However, this package only makes links from
% the reference numbers. For example, instead of linking "Fig. 1", it
% links just the "1".

% The names of sections, equations, etc.

% These reference formats work with \prettyref to associate a label name
% prefix (e.g. "fig:") with a reference format. \hyperref is used within
% each format in order to link the entire reference to its target.
%
% \autoref could be used instead of \prettyref. In that case, the \*name
% and/or \*autorefname macros would need to be redefined in a similar
% fashion and all \prettyref would have to be changed to \autoref.
% However, if this was done, it may be difficult to automatically place
% parentheses around equation numbers.
%
% NOTE: \autoref seems to have trouble with the Figure counter being
%       tied to sections, so it is best without it anyway. Use
%       hypertexnames=false as a hyperref option.
