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.
