//
// = DESCRIPTION
// This application tests the ACE Token library including local
// and remote readers/writer and mutex locks, and token
// collections. This is accomplished with the ACE Token Invariant
// utilities that allow and application to check that
// readers/writer and mutex lock invariants are always satisfied.
// Throughout this test, ACE_ASSERTs are used in conjunction with
// Token Invariant operations, so that errors are reported using
// the ACE tests convention. This application performs a local
// test and then fork_execs a token server and performs the same
// test remotely.
//
