This marks the + * beginning of historical problem of having two sets of Gaussian + * distribution computation routine, one for single-stream and one of + * multi-stream. + * + * In Sphinx 3.5, when we figure out that it is possible to allow both + * 3.0 family of tools and 3.x family of tools to coexist. This + * becomes one problem we found that very hard to reconcile. That is + * why we currently allow two versions of the code in the code + * base.
