+# Additional tests to run before releasing a package.
+#
+# Run like:
+#   make PACKAGE=/path/to/protobuf-VERSION.tar.gz
+#
+# Some of these tests require tools or make assumptions that may not be
+# available on end-user machines, so these cannot be part of "make check".  For
+# example, we test that the headers compile with strict warning settings, but
+# since different compilers produce wildly different warnings we cannot assume
+# that this test will pass everywhere.  If we ran it as part of "make check",
+# it could unnecessarily block users from running the real tests just because
+# their compiler produces some extra warnings that probably aren't a big deal.
+# So we run it separately.
