+# Problem: If a member with link count > 2 was stored in the archive twice,
+# previous versions of tar were not able to extract it, since they
+# were trying to link the file to itself, which always failed and
+# lead to removing the already extracted copy. This script tests
+# the workaround by Paul Eggert that leaves the extracted copy
+# untouched.
