 # This script is compatible with the BSD install script, but was written
 # from scratch.
 #
+# At Cygnus this script is duplicated as:
+#
+#     install.sh
+#     apache/install-sh
+#     dejagnu/install-sh
+#     expect/install-sh
+#     inet/install-sh
+#
+# if you change one of these, you will probably want to change them
+# all.  Variants of it also appear in:
+#
+#     tcl/unix/install-sh
+#     tk/unix/install-sh
+#
+# however these versions are the versions of this script from the
+# original Tcl/Tk distribution, and are somewhat different, and so
+# changing these will result in divergences from the Tcl/Tk
+# distribution.
