License Text

Public license

In short, Open CASCADE Technology Public License is LGPL-like with certain differences. You are permitted to use Open CASCADE 
Technology within commercial environments and you are obliged to acknowledge its use. You are also obliged to send your 
modifications of the original source code (if you have made any) to the Initial Developer (i.e. Open CASCADE S.A.S.). 
Complete text of the license is given below.

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.
