Update Haiku Book to refer to BeBook

These are some snippets from an email conversation with ACCESS Co., Ltd.'s General Counsel department, which was able to answer several legal questions:

For the BeBook, as you know it's released under a CC by-nc-nd/3.0. The
details of the 'no derivative works' part has been pondered by several
contributors over time. Though, the project has always stayed on the
conservative side and not taken any chances.

Would it be possible to clarify ACCESS CO.'s interpretation of what
would and would not constitute a derivative work? I'm mainly
interested to what extent the Haiku Book could refer to the BeBook, if
at all.

As an example, for sections where the BeBook accurately documents
Haiku's API, could the Haiku Book (http://api.haiku-os.org) include
text like "Refer to 'The Mail Kit - BMailMessage' in the BeBook."?

ACCESS Co., Ltd.'s General Counsel replied:

Next, as to the definition of a "derivative work", we do not have any
special opinion thereto, and the definition should be in line with 
the defintion in the US copyright law.  With respect to the matter 
specifically raised by you (for sections where the BeBook accurately
documents Haiku's API, could the Haiku Book (http://api.haiku-os.org)
include text like "Refer to 'The Mail Kit - BMailMessage' in the BeBook."?,),
we do not see any legal issue in such reference.

Based on this conversation, the Haiku Book could be populated with such entries. This would then help to identify which sections of the API need to be documented, and ideally to inspire others to contribute.
