    (description
     "ATLAS is an automatically tuned linear algebra software library
providing C and Fortran77 interfaces to a portably efficient BLAS
implementation, as well as a few routines from LAPACK.

Optimization occurs at build time.  For this reason, the library is built on
the machine where it is installed, without resorting to pre-built substitutes.

Before building the library, CPU throttling should be disabled.  This can be
done in the BIOS, or, on GNU/Linux, with the following commands:

cpufreq-selector -g performance -c 0
...
cpufreq-selector -g performance -c N-1

where N is the number of cores of your CPU.  Failure to do so will result in a
library with poor performance.")
