   classpath - Should include the at4j, bzip, lzma, entityfs-core and
               entityfs-util Jars.
   command   - The Tar command. See below.
   options   - Command options. See below.
   file      - The name and path of the Zip file to unzip.

   -t
   --list    - List the contents of the archive. This requires the "f" option.
   -x
   --extract - Extract an archive. This requires the "f" option.
 Options:
   --charset name
             - The name of the charset to use for encoding or decoding file
               names in the Tar file. If this is not set, the platform's
               default charset is used.
   -f
   --file f  - The name and path of the Tar file.
   -H format
   --format=format
             - (when creating an archive) Create an archive using the 
               specified format, where the format is one of the following:
                 'v7':    Unix V7 Tar format
                 'gnu':   Gnu Tar format (default)
                 'ustar': Posix.1-1988 compatible archive
                 'posix': Posix.1-2001 compatible archive
   -j         
   --bzip2   - The Tar file is bzipped.
   -k
   --keep-old-files
             - Don't overwrite existing files when extracting an archive.
   --lzma    - The Tar file is compressed with LZMA compression.
   --timing  - After extracting the files, print out how long it took.
   -z

The options can be used in the old tar condensed style does. For instance, xfz foo.tar.gz means "extract the gzipped Tar file foo.tar.gz".
