-For the proper proceeding you specify a String, which consists of 4 
-digits (and it may be preceded by a symbol "-"). If the String 
-begins with the "-", then a sound amplitude decreases, otherwise 
-the amplitude increases. The level of increase / decrease is 
-determined by the magnitude of the absolute value of integer numbers. 
-The greater is the number -- the greater is the amplitude change. 
-The count begins with "0000" and ends with "9999" (the sign is not 
-taken into consideration). If there is less than 4 digits in a String, 
-then the String is equivalent to that one with the appropriate number 
-of zeroes preceding to fulfill to the 4 needed digits (for example, 
-"657" is equivalent to "0657", "-2" is equivalent to "-0002" etc.). 
-In such a case, for the Strings without the initial sign "-" (the 
-sound increases) an interval between the maximum by modulus value 
-of the amlitude (which is represented by the parts of 1) and 1.0 
-is divided into 10 equal parts (starting a count from 0) and then 
-that one of them is selected, which has a number determined by the 
-first digit in the String writing. Then (if specified further) 
-the interval between this amplitude value and a value, which 
-corresponds to the selection on the previous step the next 
-first digit in the writing (for example, after "4" -- "5", 
-after "7" --"8" etc.), greater by 1 than the actually selected one, 
-is also divided again into 10 equal parts and that one is selected, 
-which corresponds to the number determined by the second digit in the 
-String writing (again beginning with "0" and ending with "9") and so on 
-until the 4th level. The greater exactness is not needed because our 
-hearing ability hardly distinguish such a subtle sound changes. If 
-the String has as a first element the "-" Char (the sound decreases), 
-then everything is analogously the same, but an interval between the 
-maximum by modulus amplitude value and 0.0 is divided into 10 equal parts 
-and so on.

-         ***** Command Line Arguments *****
-         ==================================
-         
-If you specify a command line argument (other than "-h", "-r", or "-v"),
-it must be a sorted list of the Ukrainian sounds representations,
-which can be obtained by using the mmsyn7s package. For more information,
-please, refer to:
-[mmsyn7s](https://hackage.haskell.org/package/mmsyn7s).
-
-In such a case, the program will modify only the amplitudes for

-sounds representations in the current directory.

-The "-h" command line argument is used for the help informational message.
-
-The "-v" command line argument is used for the version number.
