+// This file handles the #includes for BLAS, LAPACK and so on.
+// It manipulates the declarations into a common format that kaldi can handle.
+// However, the kaldi code will check whether HAVE_ATLAS is defined as that
+// code is called a bit differently from CLAPACK that comes from other sources.
+
+// There are three alternatives:
+// (i) you have ATLAS, which includes the ATLAS implementation of CBLAS
+// plus a subset of CLAPACK (but with clapack_ in the function declarations).
+// In this case, define HAVE_ATLAS and make sure the relevant directories are
+// in the include path.
+
+// (ii) you have CBLAS (some implementation thereof) plus CLAPACK.
+// In this case, define HAVE_CLAPACK.
+// [Since CLAPACK depends on BLAS, the presence of BLAS is implicit].
+
+// (iii) you have the MKL library, which includes CLAPACK and CBLAS.
+
+// Note that if we are using ATLAS, no Svd implementation is supplied,
+// so we define HAVE_Svd to be zero and this directs our implementation to
+// supply its own "by hand" implementation which is based on TNT code.
