Freesteel Computer Aided Manufacture Algorithms is released under the General Public License (see gpl.txt which should be with this distribution). For better integration, certain lower level functions and classes may be re-released under the FreeBSD license at a later date. The General Public License requires that anyone who has access to any compiled binaries based on this source code, in full or in part, must have free access to the source code of those full compiled binaries. This applies to the whole application even if this source code is compiled into a dynamically linked library and linked into the application separately; the whole application must make its source code public to whomever has access to it. If the application you are writing is an experimental version for testing purposes, and is seen only privately within a company, the GPL is satisfied because all the people who are within the company, who use and see the software, technically have access to the source code. The line is crossed when the software is distributed to the wider world without the full source code of the application going with it. If you would like to use this software in a proprietary system for sale and profit, please contact CIMCO Integration for a private license on reasonable and negotiable terms. All the source code in this module which is copyright Julian Todd and/or Martin Dunschen has been delivered to them under separate terms which makes this possible. When they sell the source code to you, it may look the same, and do the same thing, but it is is not the same because their copy is not distributed under the GPL and your rights will be different. If you use this software against the terms of the GPL, and you haven't obtained your copy from a source that has been authorized by the copyright holders (where-upon it will have a different license at the heading of each file), you will be found out. The Computer Aided Manufacturing market is very small, and we can recognize the behaviour of this software from a mile off, and we will come and get you for breach of copyright. It's not worth it. You should contact CIMCO and purchase it on reasonable terms. If you use this software within the terms of the GPL, in that you distribute it in other systems whose source code has also been published under the terms of the GPL, then you will have our full and unqualified support.
