% Modified version of cgloss4e.sty.  Hacked and renamed cgloss.sty
% by Alexis Dimitriadis (alexis@babel.ling.upenn.edu) 

% Following borrows from Covington's style files inspired by Midnight by M.
% de Groot, 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
%

% Changes by Alexis Dimitriadis 
%
% Removed flushleft environment and initial vskip to make macros usable
% on the same line with earlier and/or later text, e.g.,
% \item Q: \gll ... \\
%               ... \\   \hfill (Greek)
%    \trans Q: `...' 
% Note: Text following the gloss will appear on line one of the example;
% To get a line break, insert one manually with \\ or use \trans or \glt.
% (\gln does not end the line, since it was already the
% case in cgloss4e that a translation must be ended with a line break).
%
% Modified \glt to keep translation on the same page as the text.

% BUGS: does not work very gracefully with double spacing (struts are not
% automatically inserted after the \vboxes used by the macros).  
% In double space mode without \nosinglegloss, when a translation
% is not given, the next line of text is single-spaced from the glossed text.
% With \nosinglegloss, the translation is set too close to the bottom line.

%%% 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).
