% The BCP 47 language tag for that file is "mul-ethi" to reflect the fact that
% it can be used by multiple languages (and a single script, Ethiopic).  It is,
% though, not supposed to be linguistically relevant and should, for proper
% typography, be replaced by files tailored to individual languages.  What we
% do for the moment is to simply allow break on either sides of Ethiopic
% syllables, and to forbid it before some punctuation marks particular to
% the Ethiopic script (which we thus make letters for this purpose).
