+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# 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
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+OpenBLAS: OpenBLAS (an optimized BLAS library)
+OpenBLAS:
+OpenBLAS: OpenBLAS is an optimized BLAS library based on GotoBLAS2 1.13 BSD version.
+OpenBLAS: BLAS stands for Basic Linear Algebra Subprograms. BLAS provides standard
+OpenBLAS: interfaces for linear algebra, including BLAS1 (vector-vector operations),
+OpenBLAS: BLAS2 (matrix-vector operations), and BLAS3 (matrix-matrix operations).
+OpenBLAS: If the BLAS implementation is highly optimized, the whole application
+OpenBLAS: can get substantial benefit.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# 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
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+python-numpy: python-numpy (python module for scientific computing)
+python-numpy:
+python-numpy: NumPy is the fundamental package for scientific computing with Python.
+python-numpy: Besides its obvious scientific uses, NumPy can also be used as an
+python-numpy: efficient multi-dimensional container of generic data.
+python-numpy: Arbitrary data-types can be defined. This allows NumPy to seamlessly
+python-numpy: and speedily integrate with a wide variety of databases.
