 # Copy support files to the test directory. The support files are copied to a directory that is shared by all tests
 # that use the given test base name.

+#
+# TEST_NAME_BASE: The base name of the test. Returned by four_c_auto_define_tests().
+# SUPPORT_FILES: A list of files to be copied. The files are copied to the test directory. If any of the files
+#                have an .in suffix, they are configured (replacing all @VAR@ expressions) before copying.
