22 /* The following changes developed by Richard Sharpe for Canon Information
23 Systems Research Australia (CISRA)
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:
33 -TcrX file.tar "*.(obj|exe)"
35 will skip all .obj and .exe files
