+// This is just the beginning of LLVector4a. There are many more useful functions
+// yet to be implemented. For example, setNeg to negate a vector, rotate() to apply
+// a matrix rotation, various functions to manipulate only the X, Y, and Z elements
+// and many others (including a whole variety of accessors). So if you don't see a
+// function here that you need, please contact Falcon or someone else with SSE
+// experience (Richard, I think, has some and davep has a little as of the time
+// of this writing, July 08, 2010) about getting it implemented before you resort to
+// LLVector3/LLVector4.
