+      CVXOPT is a free software package for convex optimization based on the
+      Python programming language. It can be used with the interactive
+      Python interpreter, on the command line by executing Python scripts,
+      or integrated in other software via Python extension modules. Its main
+      purpose is to make the development of software for convex optimization
+      applications straightforward by building on Python's extensive
+      standard library and on the strengths of Python as a high-level
+      programming language.
