# This set of libraries are used to verify linker namespaces.

# -----------------------------------------------------------------------------
# Test cases
# 1. Check that private libraries loaded in different namespaces are
#    different. Check that dlsym does not confuse them.
# 2. Check that public libraries loaded in different namespaces are shared
#    between them.
# 3. Check that namespace sticks on dlopen
#
# Dependency tree (visibility)
# libnstest_root.so (this should be local to the namespace)
# +-> libnstest_public.so
# +-> libnstest_private.so
#
# libnstest_dlopened.so (library in private namespace dlopened from libnstest_root.so)
