      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.
