+# Run this script to link the executable with fewer direct dependencies.
+#
+# You shouldn't call this directly; instead, use the configure script's
+# --enable-link-sh option and run make normally. This isn't enabled by
+# default because there is the potential for runtime linking problems on
+# some platforms. If you have a newer version of GCC, you should prefer
+# the --as-needed linker flag over this method, though they both should
+# accomplish the same thing.
+#
+# This script was adapted from some public domain code written by Bram
+# Moolenaar for Vim. The only input needed is the link command in the
+# variable LINK. It is expected that the linker will return an error code
+# or this will not work. The script caches the test results in the
+# `.link/link.sed' file; delete that file if you want to redetermine the
+# required direct dependencies.
+#
+
+
+# List here any libraries that are known to not be needed on some platform.
