Open CASCADE Technology Public License
Version 6.6, April 2013

OPEN CASCADE releases and makes publicly available the source code of the
software Open CASCADE Technology to the free software development community
under the terms and conditions of this license.

It is not the purpose of this license to induce you to infringe any patents
or other property right claims or to contest validity of any such claims;
this license has the sole purpose of protecting the integrity of the free
software distribution system, which is implemented by public license
practices. Many people have made generous contributions to the wide range
of software distributed through that system in reliance on consistent
application of that system; it is up to the author/donor to decide if he or
she is willing to distribute software through any other system and a
licensee cannot impose that choice.

Please read this license carefully and completely before downloading this
software. By downloading, using, modifying, distributing and sublicensing
this software, you indicate your acceptance to be bound by the terms and
conditions of this license. If you do not want to accept or cannot accept
for any reasons the terms and conditions of this license, please do not
download or use in any manner this software.
