    9 # Used to create a copy of the a directory tree that has links for all non-
   10 # directories (except those named RCS).  If you are building the distribution
   11 # on more than one machine, you should use this script.
   12 #
   13 # If your master sources are located in /usr/local/src/X and you would like
   14 # your link tree to be in /usr/local/src/new-X, do the following:
   15 #
   16 #   %  mkdir /usr/local/src/new-X
   17 #   %  cd /usr/local/src/new-X
   18 #   %  lndir ../X
   19 #
   20 # Note: does not link files beginning with "."  Is this a bug or a feature?
   21 #
   22 # Improvements over R3 version:
   23 #   Allows the fromdir to be relative: usually you want to say "../dist"
   24 #   The name is relative to the todir, not the current directory.
   25 #
   26 # Bugs in R3 version fixed:
   27 #   Do "pwd" command *after* "cd $DIRTO".
   28 #   Don't try to link directories, avoiding error message "<dir> exists".
   29 #   Barf with Usage message if either DIRFROM *or* DIRTO is not a directory.
