  Description     : C++ wrappers for SIMD intrinsics

Long-Description:
 SIMD (Single Instruction, Multiple Data) is a feature of microprocessors
 that has been available for many years. SIMD instructions perform a
 single operation on a batch of values at once, and thus provide a way to
 significantly accelerate code execution. However, these instructions
 differ between microprocessor vendors and compilers.
 .
 xsimd provides a unified means for using these features for library
 authors. Namely, it enables manipulation of batches of numbers with the
 same arithmetic operators as for single values. It also provides
 accelerated implementation of common mathematical functions operating
 on batches.

The xsimd library is part of the xtensor stack. It will be maintained by
the Debian Science Team alongside the rest of the xtensor libraries.
