Euphoria Standard Library (ESL)

License

The Euphoria Standard Library is released as public domain to let all programmers use it freely and without any restrictions of any sort.

Robert Craig of RDS (the creators of Euphoria) explains public domain in simple terms in a way similar to this (modified from his resonse to questions about him having released the Euphoria source code to the official interpreter into the public domain):

You can do *anything* with the source. It's Public Domain.
You have the same rights to it as we do.
You can modify it in any way.
You can translate it.
You can sell it.
You can close source it.
You can open source it.
You can try to make a competitive product from it.
You don't even have to acknowledge us as the author
(though that would be a bit rude).

While these rights apply to everyone the ESL project has two supplemental statements:

1) While the source is completely public domain and anyone can do whatever they like with it the Euphoria Standard Library project politely asks that if you borrow/modify code from the project that you acknowledge the ESL project as the source of the code you borrowed/modified.

2) We want to remind everyone that this software comes with NO WARRANTY OF ANY KIND EITHER EXPRESSED OR IMPLIED INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. ETC.
