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