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