 /** @file
   Provides services to allocate and free memory buffers of various memory types and alignments.
-
+  
+  The Memory Allocation Library abstracts various common memory allocation operations. This library 
+  allows code to be written in a phase-independent manner because the allocation of memory in PEI, DXE, 
+  and SMM (for example) is done via a different mechanism. Using a common library interface makes it 
+  much easier to port algorithms from phase to phase.

 /** @file
   Provides library services to make PAL Calls.
-
+  
+  The PAL Library provides a service to make a PAL CALL.  This service is identical
+  in functionality to AsmPalCall() in the Itanium specific functions of the Base Library.
+  The only difference is that the  PAL Entry Point is not passed in.  Implementations
+  of this library class must manage PAL Entry Point on their own.  For example, a PEI
+  implementation can use a PPI to lookup the PAL Entry Point, and a DXE implementation
+  can contain a constructor to look up the PAL Entry Point from a HOB.  This library class 
+  is only available on IPF.
