\RequirePackage{kvoptions}

% Declared options:
%
%   BOUNCE CORE
%
%   - palette (red, blue, green, purple, cyan are the options)
%
%       The palette option will control the color scheme
%       of the document.
%
%       Blue is the default option.
%
%       If you are trying to write a collection of handouts for high school
%       math competitions, we recommend you use a consistent color scheme.
%       The authors suggest that red, blue, green, and purple correspond to
%       algebra, combo, geometry, and number theory.
%
%   - suite (diamonds, clubs, hearts, spades, and global are the options)
%
%       The suite option will determine several symbols,
%       including the section and problem symbols.
%
%       Global is the default option.
%
%   BOUNCE ADDONS
%
%   - showsol
%
%       solutions attached to exercises and pset problems are always present
%       in the source code, but only shown when showsol is called
%
%   - breakbox
%
%       if this is true, the prosol box becomes breakable

% BOUNCE CORE OPTIONS

\DeclareStringOption[blue]{palette} % for colorpalette.sty
\DeclareStringOption[global]{suite} % for symbolsuite.sty

% BOUNCE ADDON OPTIONS
