     The Modifications which You create or to which You contribute are
     governed by the terms of this License, including without limitation
     Section 2.2. The Source Code version of Covered Code may be
     distributed only under the terms of this License or a future version
     of this License released under Section 6.1, and You must include a
     copy of this License with every copy of the Source Code You
     distribute. You may not offer or impose any terms on any Source Code
     version that alters or restricts the applicable version of this
     License or the recipients' rights hereunder. However, You may include
     an additional document offering the additional rights described in
     Section 3.5.

     3.2. Availability of Source Code.
     Any Modification which You create or to which You contribute must be

     Executable version available; and if made available via Electronic
     Distribution Mechanism, must remain available for at least twelve (12)
     months after the date it initially became available, or at least six
     (6) months after a subsequent version of that particular Modification
     has been made available to such recipients. You are responsible for
     ensuring that the Source Code version remains available even if the
     Electronic Distribution Mechanism is maintained by a third party.

     3.3. Description of Modifications.
     You must cause all Covered Code to which You contribute to contain a
     file documenting the changes You made to create that Covered Code and
     the date of any change. You must include a prominent statement that
