+ This library supports a Boot Services table library implementation that allows code dependent
+ upon UefiBootServicesTableLib to operate in an isolated execution environment such as within
+ the context of a host-based unit test framework.
+
+ The unit test should initialize the Boot Services database with any required elements
+ (e.g. protocols, events, handles, etc.) prior to the services being invoked by code under test.
+
+ It is strongly recommended to clean any global databases (e.g. protocol, event, handles, etc.) after
+ every unit test so the tests execute in a predictable manner from a clean state.
