You are permitted to use Open CASCADE Technology within commercial environments and

Open CASCADE Technology Public License

Version 6.2 March, 2007

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.
