3.2. Availability of Source Code.
Any Modification which You create or to which You contribute must be made
available in Source Code form under the terms of this License either on the same
media as an Executable version or via an accepted Electronic Distribution
Mechanism to anyone to whom you made an 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 the Modification is
derived, directly or indirectly, from Original Code provided by the Initial Developer
and including the name of the Initial Developer in (a) the Source Code, and (b) in
any notice in an Executable version or related documentation in which You describe
the origin or ownership of the Covered Code.
3.4. Intellectual Property Matters
(a) Third Party Claims.
If Contributor has knowledge that a license under a third party's intellectual
property rights is required to exercise the rights granted by such Contributor under
Sections 2.1 or 2.2, Contributor must include a text file with the Source Code
distribution titled "LEGAL'' which describes the claim and the party making the
claim in sufficient detail that a recipient will know whom to contact. If Contributor
obtains such knowledge after the Modification is made available as described in
Section 3.2, Contributor shall promptly modify the LEGAL file in all copies
Contributor makes available thereafter and shall take other steps (such as notifying
appropriate mailing lists or newsgroups) reasonably calculated to inform those
who received the Covered Code that new knowledge has been obtained.
(b) Contributor APIs.
If Contributor's Modifications include an application programming interface and
Contributor has knowledge of patent licenses which are reasonably necessary to
implement that API, Contributor must also include this information in the LEGAL
file.
