research effort focusing on applying empirical techniques in order to
provide portable performance. At present, it provides C and Fortran77
interfaces to a portably efficient BLAS implementation, as well as a few

+routines from LAPACK. Nevertheless, by default, this SlackBuild also
+builds a full LAPACK linked with ATLAS. If you are really sure that you
+don't want this, set LAPACK_SOURCE to the empty string when running this

-This conflicts with cblas (only one of atlas and cblas may be installed

-README.SLACKWARE).
+This conflicts with cblas and lapack (not to be confused with lapack-atlas).
+Nevertheless, it should be possible to avoid these conflicts by proper use

-You need to read over README.SLACKWARE *before* building this.
+The impatient may just switch CPU throttling off and run the script, but
+you are advised to read over README.SLACKWARE *in advance*.
