% Using OML encoded fonts for math alphabets is one way to get
% small Greek letters in different math alphabets (cf. isomath_).
% However, there is currently no OML encoded sans-serif bold upright
% font known to the author. Therefore this package provides only
% Latin and capital Greek letters.
 
% Options are defined with the key=value interface provided by
% kvoptions_::

\RequirePackage{kvoptions}

% fontfamily
% ----------
%
% Sans-serif font family to be used for \mathsfbf. Must provide a bold
% (bx) upright (n) version in old TeX font encoding (OT1).
% Defaults to the default sans-serif font. Alternatives include 'cmss'
% and 'cmbr' (Computer Modern) and 'phv' (Helvetica):: 

\DeclareStringOption[\sfdefault]{fontfamily}
