+# Define an externally linked resource. A linked resource is an arbitrary
+# file that is linked into the test binary. The application refers to this
+# resource by name. The linked generates identifiers beg_<name> and end_<name>
+# for referencing by the C code.

+# Parameters: <unique name>, <file to be linked>
