  22 /* The following changes developed by Richard Sharpe for Canon Information
  23    Systems Research Australia (CISRA)
  24
  25    1. Restore can now restore files with long file names
  26    2. Save now saves directory information so that we can restore
  27       directory creation times
  28    3. tar now accepts both UNIX path names and DOS path names. I prefer
  29       those lovely /'s to those UGLY \'s :-)
  30    4. the files to exclude can be specified as a regular expression by adding
  31       an r flag to the other tar flags. Eg:
  32
  33          -TcrX file.tar "*.(obj|exe)"
  34
  35       will skip all .obj and .exe files
