3.2 Ansi C Stack Core Module
This module is released under the RCL Licence and includes following copyright notice, except where otherwise noted in the source code all the files are:

3.2.2 License Issues
Unless explicitly acquired and licensed from Licensor under another license, the contents of this file are subject to the Reciprocal Community License ("RCL") Version 1.00, or subsequent versions as allowed by the RCL, and You may not copy or use this file in either source code or executable form, except in compliance with the terms and conditions of the RCL.

All software distributed under the RCL is provided strictly on an "AS IS" basis, WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESS OR IMPLIED, AND LICENSOR HEREBY DISCLAIMS ALL SUCH WARRANTIES, INCLUDING WITHOUT LIMITATION, ANY WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, QUIET ENJOYMENT, OR NON-INFRINGEMENT. See the RCL for specific language governing rights and limitations under the RCL.

3.2.3 License in Short

The Ansi C Stack Core Module stays under the Reciprocal Community License (RCL) which is based on the concept of reciprocity or, if you prefer, fairness.

The RCL is adapted from the Open Source Reciprocal Public License (RPL) where the Public in the Open Source RPL license is replaced by the Community in the RCL License. In short, the RPL license grew out of a desire to close loopholes in previous open source licenses, loopholes that allowed parties to acquire open source software and derive financial benefit from it without having to release their improvements or derivatives to the community which enabled them. This occurred any time an entity did not release their application to a "third party". While there is a certain freedom in this model of licensing, it struck the authors of the RPL as being unfair to the open source community at large and to the original authors of the works in particular. After all, bug fixes, extensions, and meaningful and valuable derivatives were not consistently faster, growth and expansion of the overall open source software base. While you should clearly read and understand the entire license, the essence of the RCL is found in two definitions: "Deploy" and "Required Components".

Regarding deployment, under the RCL your changes, bug fixes, extensions, etc. must be made available to the community when you Deploy in any form -- either internally or to an outside party. Once you start running the software you have to start sharing the software.

Further, under the RCL all components you author including schemas, scripts, source code, etc. -- regardless of whether they're compiled into a single binary or used as two halves of client/server application -- must be shared. You have to share the whole pie, not an isolated slice of it.
