+LAPACK provides routines for solving systems of simultaneous linear
+equations, least-squares solutions of linear systems of equations,
+eigenvalue problems, and singular value problems.
+
+Install an optimized BLAS instead of the reference BLAS from Netlib if you
+wish to improve LAPACK's performance. Otherwise, use the BLAS build script 
+provided at Slackbuilds.org.  You may also build your own tuned lapack library
+with ATLAS.
+
+This requires blas.

+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must

+lapack: LAPACK (linear algebra routines)
+lapack:
+lapack: LAPACK provides routines for solving systems of simultaneous linear
+lapack: equations, least-squares solutions of linear systems of equations,
+lapack: eigenvalue problems, and singular value problems. The associated matrix
+lapack: factorizations (LU, Cholesky, QR, SVD, Schur, generalized Schur) are
+lapack: also provided, as are related computations such as reordering of the
+lapack: Schur factorizations and estimating condition numbers. Dense and banded
+lapack: matrices are handled, but not general sparse matrices. In all areas,
+lapack: similar functionality is provided for real and complex matrices, in
+lapack: both single and double precision.
