      Tool (wrapper) for compression and handling multiple type of archives (Zip, GZip, RAR, 7z).

      Usage: tcomp [<key>] full_path
        <key> - determines supported type of compression:
          z - use Zip
          g - use GZip (can't compress folder, only file)
          r - use RAR
          7 - use 7z

      Examples:
        tcomp z '/home/alex/The Lord of the Rings.txt'  # creates '/home/alex/The Lord of the Rings.txt.zip'
        tcomp /home/alex/Hobbit.txt.7z                  # creates /home/alex/Hobbit.txt
      }
    end
  end
