// The summary is where all the action is on this test.  Only TplClass
// should be replaceable by a forward-declare, because only it is
// exposing a symbol in a non-system namespace.

/**** IWYU_SUMMARY

tests/cxx/system_namespaces.cc should add these lines:
namespace notsys_ns { template <typename T> class TplClass; }

tests/cxx/system_namespaces.cc should remove these lines:
- #include "tests/cxx/system_namespaces-d3.h"  // lines XX-XX

The full include-list for tests/cxx/system_namespaces.cc:
#include "tests/cxx/system_namespaces-d1.h"  // for StdClass
#include "tests/cxx/system_namespaces-d2.h"  // for SystemClass
namespace notsys_ns { template <typename T> class TplClass; }
