+Module Name:
+
+  Sprint.c
+
+Abstract:
+
+  Basic Ascii AvSPrintf() function named VSPrint(). VSPrint() enables very
+  simple implemenation of SPrint() and Print() to support debug. 
+
+  You can not Print more than EFI_DRIVER_LIB_MAX_PRINT_BUFFER characters at a 
+  time. This makes the implementation very simple.
+
+  VSPrint, Print, SPrint format specification has the follwoing form
+
+  %[flags][width]type
+
+  flags:
+    '-' - Left justify
+    '+' - Prefix a sign
+    ' ' - Prefix a blank
+    ',' - Place commas in numberss
+    '0' - Prefix for width with zeros
+    'l' - UINT64
+    'L' - UINT64
+
+  width:
+    '*' - Get width from a UINTN argumnet from the argument list
+    Decimal number that represents width of print
+
+  type:
+    'X' - argument is a UINTN hex number, prefix '0'
+    'x' - argument is a hex number
+    'd' - argument is a decimal number
+    'a' - argument is an ascii string 
+    'S','s' - argument is an Unicode string
+    'g' - argument is a pointer to an EFI_GUID
+    't' - argument is a pointer to an EFI_TIME structure
+    'c' - argument is an ascii character
+    'r' - argument is EFI_STATUS
+    '%' - Print a %
