# This compares the files with those of the same name  in  dir,  and  if  any #
# $file  is  newer  than  $dir/$file,  it  is copied.  The intended use is to #
# "download" local files to a remote directory, but only for those that  have #
# been edited and are newer than their version in the remote directory.       #
#                                                                             #
# Note that the copying is done via Lc so the old versions will be backed up. #
# This can cause problems for multiply-linked file schemes.                   #
