-    ## We need to compile VCL four different times with different CXX options
-    ## for different instruction sets. As vect.cpp compiles it will produce
-    ## different function names for corresponding instruction sets.
-    ## Results of these compilations are then combined together in a single library.
-    ## This way same library will have a set of functions for each instruction sets.
-
-    ## Java will then call a dispatcher, which will check instruction set for the runtime
-    ## and fetch method pointer to the relevant implementation.
