  2. USAGE='USAGE: install_list [ -d config_prefix ] list_file mount_path map_to_path
  3.     Each line of list_file has an inode number followed by two tabs and
  4.     a file path.  Each file path starts with the string passed in 
  5.     the mount_path argument.  The file or directory is installed
  6.     at the path formed by replacing mount_path with map_to_path.
  7.  
  8.     If a file or directory is listed and its parent directory needs
  9.     to be installed, the parent directory must be in list_file also.
