+    """
+    ARPACK-NG is a collection of Fortran77 subroutines designed to solve large scale eigenvalue problems.
+
+    Important Features:
+
+    * Reverse Communication Interface.
+    * Single and Double Precision Real Arithmetic Versions for Symmetric,
+      Non-symmetric, Standard or Generalized Problems.
+    * Single and Double Precision Complex Arithmetic Versions for Standard or
+      Generalized Problems.
+    * Routines for Banded Matrices - Standard or Generalized Problems.
+    * Routines for The Singular Value Decomposition.
+    * Example driver routines that may be used as templates to implement numerous
+      Shift-Invert strategies for all problem types, data types and precision.
+
+    This project is a joint project between Debian, Octave and Scilab in order to
+    provide a common and maintained version of arpack.
+
+    Indeed, no single release has been published by Rice university for the last
+    few years and since many software (Octave, Scilab, R, Matlab...) forked it and
+    implemented their own modifications, arpack-ng aims to tackle this by providing
+    a common repository and maintained versions.
+
+    arpack-ng is replacing arpack almost everywhere.
