+It is highly recommended to install libraries implementing BLAS and LAPACK
+before installing numpy. You may choose between:
+   a) BLAS and LAPACK (reference but unoptimized and thus slow)
+   b) OpenBLAS (optimized, provides LAPACK too)
+   c) ATLAS and LAPACK (optimized), good to read README.ATLAS
+All these are available on SlackBuilds.org.
+
+If you want to use the UMFPACK library instead of SuperLU to solve unsymmetric
+sparse linear systems, then run this Slackbuild with NO_UMFPACK set to "no"
+and then install scikit-umfpack on top of scipy. In this context, UMFPACK is an
+optional dependency for numpy. Nevertheless, note that presently scikit-umfpack
+is not available on SlackBuilds.org while its dependencies are.
+
+NOTE: If you use this SlackBuild, numpy will run with the python version
+      provided by Slackware Linux, which is presently 2.7.xx. If you'd like to
+      use python 3.x then you have to install numpy with the numpy-legacy3
+      SlackBuild.
 
 IMPORTANT: This version, 1.8.2, is the latest to include the oldnumeric

+The numpy v. 1.8.2 is not able to autodetect the shared libraries created by
+newer versions of ATLAS. Thus if one lets ATLAS create these libraries, she
+has to tell numpy about them.
+
+By default the numpy-legacy script forces numpy to look for the shared, threaded
+ATLAS libraries. If you want to change this behaviour you have the following
+possibilities:
+
+a) Set ATLAS_SHARED to "no". In this case numpy will just look for the
+   apropriate static libraries.
+b) Set ATLAS_THREADS to "no". In this case numpy will be forced to look for
+   the single threaded ATLAS libraries, static or shared depending on the
+   value of ATLAS_SHARED. Otherwise it will look for the threaded ones.
