\ProvidesPackage{epltxchapno}%
  [2014/01/27 v1.0 ExPex-LaTex chapter numbering integration (JF)]
\RequirePackage{expex}

% epltxchapno.sty is for use in conjunction with LaTex classes which use
% \chapter (book.cls, scrbook.cls, report.cls, and memoir.cls at least).
% \excnt is set to 1 at the beginning of each chapter and examples are
% numbered (n.1), (n.2), etc. in chapter n.  The \deftag/\getref
% mechanism produces the desired reference.
