 % \section{What is the feature to be fixed}
-% The four languages Catalan, French, Italian and Romansh use the  apostrophe for marking
-% the vocalic elision of the ending vowel at the end of prepositions, articles, articulated
-% prepositions, definite adjectives, and other words playing similar rôles when they just
-% precede nouns, adjectives, verbs, numerals, that start with a vowel.
+% The five languages Catalan, French, Italian, Romansh, and Friulan use the  apostrophe
+% for marking the vocalic elision of the ending vowel at the end of prepositions, articles,
+% articulated prepositions, definite adjectives, and other words playing similar rôles when
+% they just precede nouns, adjectives, verbs, numerals, that start with a vowel. Probably
+% there are other languages that use the apostrophe in a similar way. I can easily upgrade
+% this small package if \LaTeX\ users of other languages let me know about such languages.
 % 
 % This feature is common to most Romance languages (from West to East) from Catalan and
 % Valencian, to French, Langue d'oc, Occitan, Provençal, Vivaroalpin, Italian, Piedmontese,
 % Lombard, Romansh, Ladin, Friulian; up to now only Catalan, French and Italian are handled
 % by the \TeX\ system programs; at the same time most of these languages are minority ones
 % and are being protected by local legislation or are supported by specific cultural or

-% Switzerland and is being used in legal and official documents in the Swiss Confederation,
