-x<filespec>    Exclude files from extraction
  -x@list.lst     Exclude list of files from extraction

  By specifying a -x as part of the PKUNZIP command, you may prevent a file
  or group of files from being extracted.  Using -x with a list file will
  allow you to exclude a list of files from extraction.

     pkunzip fd201.zip -x*.doc

  In this example all files are extracted from the .ZIP file "fd201.zip"
  except for those with a ".doc" extension.

  -x may be used more than once on the command line, and may be used in
  combination with specific filespecs and list files.
