			      ABSTRACT


TREEDUPL duplicates all directories and files in an MS-DOS directory 
tree rooted at some point to a directory tree rooted at some other 
point.  If old versions of the files from the source directory tree 
are present in the target directory tree, they are replaced by the 
files from the source;  if files in the target directory tree are not 
present in the source directory tree, the files in the target 
directory tree may optionally be deleted.

In a DECnet-Rainbow or DECnet-DOS environment, TREEDUPL may be used to 
back up a local hard disk to a network virtual disk, and to restore 
the local hard disk from the network virtual disk.
