+ """XBLAS is a reference implementation for extra precision BLAS.
+
+ XBLAS is a reference implementation for the dense and banded BLAS
+ routines, along with extended and mixed precision version. Extended
+ precision is only used internally; input and output arguments remain
+ the same as in the existing BLAS. Extra precisions is implemented as
+ double-double (i.e., 128-bit total, 106-bit significand). Mixed
+ precision permits some input/output arguments of different types
+ (mixing real and complex) or precisions (mixing single and
+ double). This implementation is proof of concept, and no attempt was
+ made to optimize performance; performance should be as good as
+ straightforward but careful code written by hand."""
