The Bento Poetic License


The intent of this document is to state the conditions under which a Package may be copied, such that the Copyright Holder maintains control over the Language Specification which the Package implements, while while giving the users of the Package the right to use and distribute the Package in any fashion, including the right to make any modifications that do not contradict the Language Specification.


  • "Package" refers to the collection of files distributed by the Copyright Holder, and derivatives of that collection of files created through textual modification.
  • "Language" refers to the computer language which the Package implements.
  • "Language Specification" refers to the grammar and normative documentation which defines the Language.
  • "Copyright Holder" is whoever is named in the copyright or copyrights for the Package.
  • "You" is you, if you're thinking about copying or distributing this Package.
  • "Contradict the Language Specification" means to modify the Package in such a way that a user wishing to access one or more features of the Package would have no choice but to write code which is illegal according to the Language Specification.

    Failure to comply with the Language Specification is NOT the same as contradicting the Language Specification. The Language Specification represents a target, and every implementation is a work in progress. You are not required to ensure that legal code works, only that illegal code fails.

    Failure to keep up with the Language Specification is NOT the same as contradicting the Language Specification. Code which is legal for any version of the Language Specification, even if it is illegal in a newer version, is not considered illegal.

    Adding requirements is NOT the same as contradicting the Language Specification. Code that requires a custom implementation or the presence of specific libraries, files, devices or other resources to work properly is not considered illegal.

1. You may make and give away verbatim copies of the source form of the Package without restriction, provided that you duplicate all of the original copyright notices and associated disclaimers.

2. You may modify the Package in any manner which does not contradict the Language Specification, except that you may not remove copyright notices or disclaimers from the source files.

3. You may modify the Package in a manner which contradicts the Language Specification, provided that you retain all copyright notices and disclaimers, and provided that you do at least ONE of the following:

a) remove all claims of compatibility with or support for the Language from the Package and all documents and materials you distribute with the Package, include a clear description of how the modified Package contradicts the Language Specification, and rename all modified classes and files so the names do not conflict with the original classes and files.

b) use the modified Package only within your corporation or organization.

c) make other distribution arrangements with the Copyright Holder.

4. The files supplied as input to or produced as output from the programs of this Package do not automatically fall under the copyright of this Package, but belong to whomever generated them. Any such files which were generated by the Copyright Holders and are included with this do fall under the copyright of this Package.

5. The name of the Copyright Holder may not be used to endorse or promote products derived from this software without specific prior written permission.


The End
