[License-discuss] For Public Comment: The Contribution Public License

I've incorporated several new suggestions and attached the new draft as 

- More verbose initial paragraph that's explicit about both copyright and 
patent license grants
- copyright notice -> contributor notice
- "use or distribute this software with it" in clause 2 -> "use the hereby 
granted rights"
- more explicit/verbose clause 3
- rewording of the long form copyright/patent paragraphs at the end (before 
the warranty paragraph)

Also, due to a name clash on CPL I somehow missed once the license I'll rename 
it soonish (once I can think of a new name).

Any additional feedback would be welcome.

Thank you for your time.

  You may do everything with this software that would otherwise infringe
  either any contributors' copyright in it, any patent claim any
  contributor can license that covers this software as of that
  contributor's latest contribution, or both, in exchange for your
  promise to fulfill all of the following obligations:

  1. Ensure everyone who receives a copy of this software from you, in
     any form, also receives the text of this license and the
     contributor and source notices above.

  2. License each change you make to this software under this license,
     publish it in its original form through a freely accessible
     distribution system commonly used for similar changes, and ensure
     reasonable availability of it via one such publication for as long
     as you use the hereby granted rights, but no less than 30 days.

  3. Do not make any legal claim against anyone for infringing any
     patent claim they would infringe by using this software alone,
     accusing this software, with or without changes, alone or as part
     of a larger application.

        You are granted a perpetual, universal, non-exclusive,

        software and licensable by respective contributors without
        other scope limitations.

        There is no warranty for this software, to the extent
        permitted by applicable law. Except when otherwise stated

        In no event, unless required by applicable law or agreed
        to in writing, will any copyright holder, or any other
        party who makes changes to and/or distributes this
        software as permitted above, be liable to you for damages,
        including any general, special, incidental, or
        consequential damages arising out of the use or inability

        data or data being rendered inaccurate or losses sustained
        by you or third parties or a failure of this software to
