    3. tar now accepts both UNIX path names and DOS path names. I prefer
       those lovely /'s to those UGLY \'s :-)
-   4. the files to exclude can be specified as a regular expression by adding
-      an r flag to the other tar flags. Eg:
 
-         -TcrX file.tar "*.(obj|exe)"
-
-      will skip all .obj and .exe files
