  X. Incorporating PKWARE Proprietary Technology into Your Product
  ----------------------------------------------------------------

  PKWARE is committed to the interoperability and advancement of the
  .ZIP format.  PKWARE offers a free license for certain technological
  aspects described above under certain restrictions and conditions.
  However, the use or implementation in a product of certain technological
  aspects set forth in the current APPNOTE, including those with regard to
  strong encryption, patching, or extended tape operations requires a 
  license from PKWARE.  Please contact PKWARE with regard to acquiring
  a license.

This is annoying.
