The executable mmsyn7h is auxiliary for the mmsyn7ukr package
(https://hackage.haskell.org/package/mmsyn7ukr). 
It works similarly to the mmsyn6ukr executable, but uses the voice 
sound files in the current directory. This allows to change the 
needed files and to produce them by some other means (e. g. by 
mmsyn7ukr).
Besides, you can remove the created by mmsyn7ukr and mmsyn7h files
while the last one is running.

The program mmsyn7h plays the newly created file once. Then it can delete 
the sound files in the current directory while being executed if the
entered text starts with "0". If you enter as a first command line
argument "-h", then the program prints informational message and
is terminated (killed) successfully. If you specify as a first command
line argument "-v", then the program prints its version number and is
also successfully terminated. If you specify something else, the first
command line argument is being treated as a name for the resulting
file voiced. If you specify further command line arguments as a
Ukrainian text, that contains only those sounds, which sound
representations are in the current directory (you can create them
by e. g. mmsyn7ukr and mmsyn7l programs in the same name packages),
then the program will use only these sounds representations
additionally to the default ones "-.wav", "0.wav" and "1.wav"
and produce the sounding for the text.
For more information, refer to:
https://hackage.haskell.org/package/mmsyn7ukr
https://hackage.haskell.org/package/mmsyn7s
https://hackage.haskell.org/package/mmsyn7l
In such a case the program will not delete the created resulting 
sound files.

If you do not specify the Ukrainian text as the third and the next command line
arguments, then the resulting file will be played just after it is created
by the program. To remove all the created sound files from the directory,
please, specify now the first character in the input as "0". Otherwise,
the program will not remove any records (if they are not overwritten).
