% -*- LaTeX -*-
% Following borrows from Covington's style files inspired by Midnight by M.
% van der Goot, adapted to be used with gb4e.sty: examples beginning with \ex can
% contain glosses directly. Default is
% Linguistic Inquiry style with all lines in \rm; to change a line (eg. to
% \it for a particular journal, change the appropriate line: e.g.,
% \let\eachwordone=\rm in a copy of this file. Note that it will NOT work
% to put \it before the line as the words are parsed separately.
% Use \singlegloss to force single-spaced glosses even in double-space
% environments. Works also in footnotes (^M as delimiter replaced by
% \\)---hpk
%
%%%
%%% Sentences with word-by-word glosses
%%%
% See covingtn.tex for full documentation. Some examples:
%
% Displayed sentence with gloss and translation:
%
% \gll Dit is een Nederlands voorbeeld.\\
% This is a Dutch example.\\
% \glt `This is an example in Dutch.'
%
% Same, using bracketing where words do not correspond one-to-one:
%
% \gll Dit is een voorbeeldje in het Nederlands.\\
% This is a {little example} in {} Dutch.\\
% \glt `This is a little example in Dutch.'
%
% If you want to align 3 lines rather than two, use \glll instead of \gll.
%
% Layout is critical between \gll (or \glll) and \glt (or \gln).
%
