+// e32test\misc\t_uid.cpp
+// Overview:
+// Test handling of UIDs (Unique Identifiers). 
+// API Information:
+// TUid, TUidType, TCheckedUid.
+// Details:
+// - Assign some globally unique 32-bit numbers with specified values, 
+// get standard text form of the UID and check it is as expected.
+// - Set the specified Uid type to be packaged and verify
+// - validity of UID type. 
+// - Uid type contained is as expected.
+// - component UIDs are same as specified UID.
+// - the most derived UID is as expected.
+// - Check the process' Uids are as expected.
+// - Load the specified DLL, get Uid of DLL, name of this DLL's file,
+// compare the name with a specified text and check it is as expected,
+// verify the Uid is as expected.
+// Platforms/Drives/Compatibility:
+// All 
+// Assumptions/Requirement/Pre-requisites:
+// Failures and causes:
+// Base Port information:
