class RRcppblaze(RPackage):
"""'Blaze' is an open-source, high-performance C++ math library for dense
and sparse arithmetic.
With its state-of-the-art Smart Expression Template implementation 'Blaze'
combines the elegance and ease of use of a domain-specific language with
'HPC'-grade performance, making it one of the most intuitive and fastest
C++ math libraries available. The 'Blaze' library offers: - high
performance through the integration of 'BLAS' libraries and manually tuned
'HPC' math kernels - vectorization by 'SSE', 'SSE2', 'SSE3', 'SSSE3',
'SSE4', 'AVX', 'AVX2', 'AVX-512', 'FMA', and 'SVML' - parallel execution by
'OpenMP', C++11 threads and 'Boost' threads ('Boost' threads are disabled
in 'RcppBlaze') - the intuitive and easy to use API of a domain specific
language - unified arithmetic with dense and sparse vectors and matrices -
thoroughly tested matrix and vector arithmetic - completely portable, high
quality C++ source code. The 'RcppBlaze' package includes the header files
from the 'Blaze' library with disabling some functionalities related to
link to the thread and system libraries which make 'RcppBlaze' be a
header-only library. Therefore, users do not need to install 'Blaze' and
the dependency 'Boost'. 'Blaze' is licensed under the New (Revised) BSD
license, while 'RcppBlaze' (the 'Rcpp' bindings/bridge to 'Blaze') is
licensed under the GNU GPL version 2 or later, as is the rest of 'Rcpp'.
Note that since 'Blaze' has committed to 'C++14' commit to 'C++14' which
does not used by most R users from version 3.0, we will use the version 2.6
of 'Blaze' which is 'C++98' compatible to support the most compilers and
system."""
