Open CASCADE Technology Public License
License version: 6.6 March, 2013

Open CASCADE S.A.S. 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.
