%% This file is an example of how the various penalties and spacings can be changed to tweak the 
%% overall look of a Gregorio score.  
%%
%% When customizing this file to your own use, you do not need to include all the penalties and 
%% distances listed below. Those not included will fall back onto their default values.
%%
%% The name of all space configuration files should start with `gsp-` and end with `.tex`; what goes 
%% in between is up to you (so long as it doesn’t contain spaces).  To load a space configuration 
%% file called `gsp-sample.tex`, use `\greloadspaceconf{sample}`.  The defaults can be reloaded 
%% with `\greloadspaceconf{default}`.
%%
%%%%%%%%%%%%%%%%%%%%%%%%%


%%%%%%%%%%%%%%%%%%%%%%%%%
%%
%% At the risk of oversimplifying, penalties affect line breaks: larger penalties indicate that line 
%% breaks should be less likely at the corresponding location, smaller penalties (including negative 
%% values) indicate that line breaks are more likely.

% see http://tug.org/pipermail/luatex/2013-July/004516.html
% The idea is that we use discretionaries (explicit hyphens, though more than hyphens in our case) for clef changes, and we need to give them a special penalty, which is not taken into account if pretolerance is > -1 on LuaTeX < 0.80. For a more detailed explanation see http://tug.org/pipermail/luatex/2013-July/004516.html.

%% The following spacings govern the distance between various elements (names are chosen to 
%% indicate when each spacing is used).  The macro for changing distances is \grechangedim and 
%% it takes 3 arguments:
%%
%%    (1) the name of the spacing to be changed
%%    (2) the value of the spacing
%%    (3) either `scalable` or `fixed` to indicate how the spacing should behave when 
%%           `\grechangestaffsize` is invoked.  If `scalable` then the spacing is proportionally rescaled;
%%            if `fixed` it will remain at its given value; if `inherited` then #2 should be the name of
%%         another spacing from which this spacing derives its value.
%%
%%%%%%%%%%%%%%%%%%%

%This count tells gregoriotex what size staff the below values correspond to.
%% The default staff size is 17.  At this size the scores should be approximately the size usually 
%% seen in a gradual.
%% If you’re creating your own space configuration file, you may set this to some other value, 
%% should you so desire.
%% If the current staff size doesn’t match the value given here when the spacing file is loaded, then 
%% all scalable distances will be rescaled appropriately.
