              Counting used registers (HMM)]

%% Allows to count the number of used registers
%% (counter, dimen, skip, muskip, box, token, input, output,
%%  math families, languages, insertions)
%% and compare these to the maximum available number of such registers.

\RequirePackage{kvoptions}[2010/12/23]% v3.10

%% regstats may work with earlier versions of LaTeX and these
%% packages, but this was not tested. Please consider updating
%% your LaTeX and packages to the most recent version
%% (if they are not already the most recent version).
