A: Remove Viivi System Directory

Remove the Viivi system directory.

1. First of all, see the files inside the Viivi system directory in which Viivi was installed, and confirm if they can be removed.

   	$ ls -la ${HOME}/Viivi/⮠		for Unix-like platforms (sh system) ($ is the shell prompt)
   	% ls -la ${HOME}/Viivi/⮠		for Unix-like platforms (csh system) (% is the shell prompt)
   	> dir C:\usrs\ilma\Viivi⮠		for Windows platforms (> is the cmd prompt)
   

   If you find important files (Scheme source files, text files, data files, and etc.) other than the Viivi system files there, please move them into a different directory, or take a backup.


2. When you have confirmed that the Viivi system directory can be removed, remove the Viivi system directory.
   [Caution!]
   If the following operation is performed, then the Viivi system directory and all the files in it will disappear.
   

   	$ rm -rf ${HOME}/Viivi/⮠			for Unix-like platforms (sh system) ($ is the shell prompt)
   	% rm -rf ${HOME}/Viivi/⮠			for Unix-like platforms (csh system) (% is the shell prompt)
   	> rmdir /S /Q C:\usrs\ilma\Viivi⮠	for Windows platforms (> is the cmd prompt)
   



3. Check that the Viivi system directory is removed.

   	$ ls -la ${HOME}/Viivi/⮠			for Unix-like platforms (sh system) ($ is the shell prompt)
   	% ls -la ${HOME}/Viivi/⮠			for Unix-like platforms (csh system) (% is the shell prompt)
   	> dir C:\usrs\ilma\Viivi⮠			for Windows platforms (> is the cmd prompt)
