\def\ExPexMessage
   {5/1/2017 v5.1a ExPex linguistics example formatter (JF)}
% -------------------------------------------------------
% jf 2011/12/09  (v4.0a)
%  1) fixed bug in how exceptional gla items are detected
%  2) added everytrailingcitation parameter
%  3) made \glft a long definition to allow \par
%  4) fixed bug in \printrbrack and \printlbrack, now not math mode
% jf 2011/12/09  (v4.0b)
%  1) allow {} gla item
% jf 2012/03/10  (v4.0c)
%  1) fixed problem with IJAL \deftaglabel caused by nonexpansion
%     of \@actualexno
% jf 2012/12/01  (v4.1)
%  1) added auto glskip mode to glosses
%     /abovemoreglskip/ now obsolete
%  2) fixed bug in \@setinckey so that value is expanded when set
% jf 2013/01/13  (v4.1a)
%  1) added \let\pageno=\c@page to LaTex specializations
% jf 2013/06/27  (v4.1b)
%  1) fixed bug in skip over \glft entries
% jf 2013/07/27
%  1) LaTex \include/\includeonly mechanism now works for \excnt
% jf 2013/10/08
%  1) revise the definition of \glw@printcol (now named
%   \glw@printglword) to use token lists rather than edefs, and to build
%   glwords as \vtop{\halign{#\hfil\cr...} structures
%   rather than stacked hboxes. This allows items like {\hfil
%   word}, which results in center alignment.
%   2) removed w from the prefix in \glw@append, \glw@lop, and
%   \glw@lopff since these will be used in other gloss styles
% jf 2013/10/10 fixed belowpreambleskip bug
% jf 2014/01/27  (v5.0)
%   MAJOR REVISIONS: vertical spacing in glosses, introduction of
%   nlevel style glosses (see User's Manual, also revised at this time)
%   for more detail about the changes
% jf 2014/03/08  (v5.0b)
%   1. restored allowing {} empty items in wrap glosses
%   2. introduced <glbreaking> parameter
% jf 2014/03/14  (v5.0c)
%   1. fixed reference for IJAL style
%   2. fixed initialization for roman number parts in \pex
% jf 2015/01/06  (v5.0d)
%   glftpos=right now works with the nlevel style
%   many internal names were changed to the general form
%     \gl@<style>@<ftpos>@<name> to make the code for switching style and
%     ftpos much more transparent
% jf 2015/09/30  (v5.0e)
%   right panel in nlevel style
% jf 4/11/2016  (v5.0f)
%   fixed \ep@setlist so that it does not make global asssigment
%   changed some names of the append commands to better fit their effect
% jf 3/9/2017   (v5.1)
%   fixed bug so that \glbreaking works if extraglskip has stretch and/or
%   shrink components
% jf 5/1/2017   (v5.1a)
%   1. made \sc equivalent to \scshape if the LaTex engine is used
%   2. made \it equivalent to \itshape if the LaTex engine is used
%   3. fixed bug in \getref in the IJAL style
