IT IS NOT PROHIBITED TO COPY AND DISTRIBUTE VERBATIM COPIES OF THIS LICENSE.

PREAMBLE

We maintain that there’s no necessity to alter this license for those who intend to utilize, augment, or create derivative works from our original covered work. Consequently, we’ve set forth specific guidelines for the distribution of any such derivative works. Any distributed improvements or derivatives must adhere to the same licensing terms as our original work.

We encourage your contributions to our original work, helping you to prevent dependency on your outdated versions as we anticipate a single primary code branch, from which all derivatives will emerge. Otherwise, this license also lets you use our work in “closed-source” projects, or other methods that safeguard your derivative works, provided you do not distribute a derivative work as distribution must be exclusively licensed under this license.

This license unifies us against fragmentation, enabling continuous enhancement while permanently adhering to our original terms. We expect the same from you. Copyright holders reserve all rights to protect this work and derivative works covered by this License.

In instances where the Covered Work or a Derivative Work is integrated into a system comprising works governed by various licenses, it is permissible, as an exception, to aggregate the Covered Work or a Derivative Work on a single medium.
