+AT_SETUP([incremental restores with -C])
+AT_KEYWORDS([incremental extract incr07])
+
+# Tar 1.26 had problems extracting from incremental restores when given
+# the -C option.  The code in incremen.c:try_purge_directory and
+# misc.c:remove_any_file was using savedir(), which ignored eventual changes
+# in the current working directory and caused the malfunctioning.
+#
+# The problem was reported by Piotr Rotter on 2013-03-22.
+#
+# This testcase is based on scripts provided by Piotr Rotter and Nathan
+# Stratton Treadway.
