// MACROS

// ----------- Info -----------
//
// Any macro with EXIT in it should only be used in a panic situation. It
// is synonymous with assert. If the test behaves as expected, it
// should call one of the FINISH macros.
//
// - Compound testcases
// If a testcase is capable of being part of a compound, then the following
// rules apply:
// - The testcase must only ever call one of the EXIT macros if it decides
//   the state of the system is such that further testing is meaningless;
//   such a call would prevent subsequent tests in the compound from being
//   run.
// - In order to terminate the test, the testcase should call one of the
//   FINISH macros. This must be done from within main().




// The following is the testcase API to be used by testcases.
