+// e32test\prime\t_sem.cpp
+// Overview:
+// Test the RSemaphore type.
+// API Information:
+// RSemaphore
+// Details:
+// - Create two local semaphores, create a new thread, signal and wait on 
+// the semaphores numerous time. Kill the thread and verify results.
+// - Test creating a local semaphore with an initial count of -1. Verify 
+// failure results are as expected.
+// - Attempt to signal a semaphore without having done a create. Verify 
+// failure results are as expected.
+// - Attempt to signal a semaphore with signal count of -1. Verify failure
+// results are as expected.
+// Platforms/Drives/Compatibility:
+// All.
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
