In one sentence

Broad reuse — including inside proprietary products — in exchange for keeping notices intact.

Using NCSA code

You can

  • Use the code commercially, privately, and inside closed-source products
  • Modify it and distribute your modified version
  • Sublicense it as part of a larger work under your own terms

You must

  • Keep the original copyright notice and license text with copies you distribute
  • State the license of the incorporated code in your distribution or docs

You cannot

  • Strip required notices or claim you wrote the original work
  • Expect a warranty, support, or liability cover from the authors
  • Imply the authors endorse your product

This is not legal advice. Your obligations depend on how you use the code and your jurisdiction. Consult counsel for production risk.
