+// Build test helper libraries for linker namespaces for allow all shared libs
+//
+// This set of libraries is used to verify linker namespaces for allow all
+// shared libs.
+//
+// Test cases
+// 1. Check that namespace a exposes libnstest_ns_a_public1 to
+//    namespace b while keeping libnstest_ns_a_public1_internal as an
+//    internal lib.
+// 2. Check that namespace b exposes all libraries to namespace a.
+//
+// Dependency tree (visibility)
+// libnstest_ns_b_public2.so  (ns:b)
+// +-> libnstest_ns_a_public1.so  (ns:a)
+//     +-> libnstest_ns_a_public2_internal.so  (ns:a)
+//     +-> libnstest_ns_b_public3.so  (ns:b)
