END OF TERMS AND CONDITIONS
APPENDIX: How to apply the Falcon Programming Language License to your work
To apply the Falcon Programming Language License to your work, attach the following boilerplate notice, with the fields enclosed by brackets "" replaced with your own identifying information. (Don't include the brackets!) The text should be enclosed in the appropriate comment syntax for the file format. We also recommend that a file or class name and description of purpose be included on the same "printed page" as the copyright notice for easier identification within third-party archives.
APPENDIX: License commentary
First of all, thanks for considering using The Falcon Language for Your job, or to embed it into Your application, or to use it for any other reason. The Falcon Programming Language License explains what You are allowed to do with Falcon and what You are supposed (and allowed) not to do. Since the legal jargon may be cryptic, You are provided here with a little resume of the License. It is important that You read and accept the License, as this resume hasn't any legal valence, and is provided only for the reason to express clarifications and examples that cannot find their place in the formal document.
The License grants You the rights to use the Source code of Falcon and its various components in any way; You can study it, You can copy it, You can modify it, and You can even sell it, but You can't change the license under which it is distributed: even if You sell it, You have to provide the customers with the source code of Falcon and to grant them the same rights You have on it.
The License also grants Your copyrights and intellectual rights for any modification or addition You may want to apply to Falcon. In case or addition and modifications, the License binds You to provide the user with the information that the original program, that is Falcon, was modified by You and what are the changes or the additions that You applied.
Also, even if You can freely distribute, or even charge a fee, for Your derived work, You MUST apply the Falcon Programming Language License to Your modifications, and distribute them under the same terms. In other words, Your modifications, if made public, must be provided or available in source code.
The license also grants You the right to embed Falcon in any application. Here You are granted the right to pick the terms and licenses You prefer, and to distribute Your embedding application without providing its source code. Even if significant portions of Falcon are in line functions, and even if You decide to statically link Falcon in Your application, this doesn't make it a "Derivative Work" of it: Your Embedding application is free to embed Falcon "as is" as it wish, without any requirements in terms of source distribution. You can also modify Falcon for Your specific needs and THEN embed Your modified version; the modified version of Falcon is under Falcon License, and must be made available in source code (or be proposed as a Contribution to the Falcon Committee), but Your Embedding application can still be distributed under Your preferred terms. The License has only a requirement that is demanded on Your Embedding application: in case you don't distribute your embedding application isn't made available in source code, You HAVE to state somewhere (in a place that CAN possibly be seen by the average user) that You are embedding Falcon and the reason for that. In example, You may state "ProgramX uses the Falcon Programming Language to automatize the Gamma procedure".
About the scripts, which are more or less what a scripting language is for, You are granted the right to apply the license You prefer. As Falcon is also a script "compiler", You may even retain from distributing the script sources, and apply closed-source license to Your script-based application or to the scripts that are embedded in Your embedding application. However, if You don't distribute the script sources, and you use Falcon or another application covered by the same license to run them, You are again required to state somewhere in Your documentation or where the user can read it that You are using "Falcon" (or the derivative work you used), and more or less why You are doing it. For a pure Falcon application, You can just state "This application is written in Falcon". In example, if You use Falcon to drive a web site, and You don't want Your site visitors to ever see Your scripts, You have to put somewhere a reading like "Powered with Falcon".
What You cannot do is to claim that any thing You learnt from Falcon is Yours: especially, You are forbidden to patent any element that is found in Falcon. Another thing that You can't do is to sell a Falcon based product as if it were "completely" Yours, forgetting to cite, even in a very small reading, the fact that Falcon is in. Finally, a thing that the License prevents You from doing is to put the blame for failures on Falcon: the product is provided as-is, without any warranty. It's up to You to test if it is suitable to solve Your problems, and if a Falcon based application can be sold and granted as "working" to Your customers. If that application breaks, whether there's a problem with Falcon or not, You can't issue any claim on the Falcon contributors.
Be kind on the Open Source Community: they have already made a lot for You even if You don't know them (and even if they don't know You).
