+* Third version revised B. Separated the "1" option into two different ones: "1" and "-1", each of which prints either a list of Strings or the rest of the text being
+treated partially till the first duplicated Ukrainian sound representation (except the silent ones). Improved formatting for the documentation.

 -- and prints the sorted list of the Ukrainian sounds representations that can be used further in mmsyn7 series of programs.

 -- Depending on the first command line argument the program behaves as follows:
+-- 
 -- \"-h\" -- prints help and exits;
+-- 
 -- \"-v\" -- prints version number and exits;
+-- 
 -- \"1\"  -- prints the list of String being unique (without silence) and then the rest of the text with whitespaces and some phonetical conversions;
+-- 
+-- \"-1\" -- prints the rest of the text after the first duplicated sound representation (except silent ones) including it with whitespaces and some phonetical conversions;
+-- 
 -- \"0\"  -- prints the list of String for the whole text.
+-- 
 -- All other variants of the beginning for the command line arguments are the same as \"0\" (the arguments are treated as a Ukrainian text
 -- and processed as a whole one object).
