// The following class LLWinImm delegates Windows IMM APIs.
-// We need this because some language versions of Windows,
-// e.g., US version of Windows XP, doesn't install IMM32.DLL
-// as a default, and we can't link against imm32.lib statically.
-// I believe DLL loading of this type is best suited to do
-// in a static initialization of a class. What I'm not sure is
-// whether it follows the Linden Conding Standard...
-// See http://wiki.secondlife.com/wiki/Coding_standards#Static_Members
+// It was originally introduced to support US Windows XP, on which we needed
+// to dynamically load IMM32.DLL and use GetProcAddress to resolve its entry
+// points. Now that that's moot, we retain this wrapper only for hooks for
+// metrics.
