  usage: tar.py [-h] [-t TARFILE] [-p PATH] [-f FILES] method
  
  TAR file compression/decompression using GZIP.
  
  positional arguments:
  method                What to do, either 'compress' or 'decompress'
  
  optional arguments:
  -h, --help            show this help message and exit
  -t TARFILE, --tarfile TARFILE
                          TAR file to compress/decompress, if it isn't specified
                          for compression, the new TAR file will be named after
                          the first file to compress.
  -p PATH, --path PATH  The folder to compress into, this is only for
                          decompression. Default is '.' (the current directory)
  -f FILES, --files FILES
                          File(s),Folder(s),Link(s) to compress/decompress
                          separated by ','.
  

• If you want to compress one or more file(s)/folder(s):

  python tar.py compress -f test_folder,test.txt
  

  This will compress the folder test_folder and the file test.txt into a single TAR compressed file named: test_folder.tar.gz If you want to name the TAR file yourself, consider using -t flag.
• If you want to decompress a TAR file named test_folder.tar.gz into a new folder called extracted for instance:

  python tar.py decompress -t test_folder.tar.gz -p extracted
  

  A new folder extracted will appear that contains everything on test_folder.tar.gz decompressed.
