[En-Nut-Discussion] Nut/OS license terms

[Henrik Maier]

I cames across two different license terms in the software and like to 
clarify the current applicable terms of Nut/OS usage in regards to 
section 3:

Version A:

3. All advertising materials mentioning features or use of this
    software must display the following acknowledgment:

    This product includes software developed by egnite Software GmbH
    and its contributors.

OR

Version B:

3. Neither the name of the copyright holders nor the names of
    contributors may be used to endorse or promote products derived
    from this software without specific prior written permission.

Which of the two applies currently? One says basically don't mention 
Egnite the other says you must? Confusing for me as I want to do the 
right thing.

I think Version B's usage is quite clear, for Version A however 1) what 
should users using Nut/OS in embedded products do and 2) what should 
manufacturers of compatible boards do to comply with Version A [in 
practical terms, e.g. stating the acknowledgment in manual, data sheets 
or web site etc.]?
