+This is the home of the Generic Performance Primitives, a blatant
+knock-off of intel's Integrated Performance Primitives, but with
+support for X86, PowerPC and Cell too.

+Notes on alignment:
+
+You may assume no more strict alignment than this for the arguments:
+
+ Gpp8s *   (== int8_t)             1 byte aligned
+ Gpp16s *  (== int16_t)                    2 byte aligned
+ Gpp32s *  (== int32_t)                    4 byte aligned
+ Gpp32f *  (== float)              4 byte aligned
+ Gpp64f *  (== double)             8 byte aligned
+
+ Gpp16sc * (== complex<int16_t>)    4 byte aligned (real then imag)
+ Gpp32sc * (== complex<int32_t>)    8 byte aligned (real then imag)
+ Gpp32fc * (== complex<float>)      8 byte aligned (real then imag)
+ Gpp64fc * (== complex<double>)    16 byte aligned (real then imag)
