+If your program has NUnit tests, set the variable HAS_NUNIT_TEST:
+
+========================================
+PROGRAM = myprogram.exe
+LOCAL_MCS_FLAGS = /r:System.Xml.dll
+HAS_NUNIT_TEST = yes
+include ../build/executable.make
+========================================
+
+HAS_NUNIT_TEST tests follow library.make NUnit test conventions:
+the files should be in a subdirectory called Test/, and if
+your program is called myprogram.exe, they should be listed in
+myprogram_test.dll.sources. The names in that files should *not* have
+the Test/ prefix. 'make test' will build myprogram_test_$(PROFILE).dll
+in the current directory, automatically supplying the flags to
+reference the original program and NUnit.Framework.dll.
