  The openNURBS Initiative provides CAD, CAM, CAE, and computer

  graphics software developers the tools to accurately transfer

  3-D geometry between applications.



  The tools provided by openNURBS include:



    * C++ source code libraries to read and write the file format.



    * Quality assurance and revision control.



    * Various supporting libraries and utilities.



    * Technical support.



  Unlike other open development initiatives, alliances, or

  consortia:



    * Commercial use is encouraged.



    * The tools, support, and membership are free.



    * There are no restrictions. Neither copyright nor copyleft

	  restrictions apply.



    * No contribution of effort or technology is required from

	  the members, although it is encouraged.



  For more information, please see <http://www.openNURBS.org>.



  The openNURBS toolkit uses zlib for mesh and bitmap compression.

  The zlib source code distributed with openNURBS is a subset of what

  is available from zlib.  The zlib code itself has not been modified.

  See ftp://ftp.freesoftware.com/pub/infozip/zlib/zlib.html for more 

  details.



  Zlib has a generous license that is similar to the one for openNURBS.

  The zlib license shown below was copied from the zlib web page

  ftp://ftp.freesoftware.com/pub/infozip/zlib/zlib_license.html

  on 20 March 2000.
