Features

• Universal donors.
• Universal recipients.

• No liability.
• No attribution required.

Rationale

• Shortest free clause (from BSD license)
• Shortest legal text (from ZLIB license)
• If both sections above are orthogonal and OSI/FSF/GPL/DFSG compatible, this license should be OSI/FSF/GPL/DFSG compatible as well.
