Right, understood.

Seen the examples, it is more convincing now.

So, I understand the need. Now, I am wondering whether we should have
one single variable with "special" values as Luca/you suggest, or two
clearly separated boolean variables that control each aspects
(distribute the source, include in legal-info). Example:

<pkg>_GENERATE_LEGAL_INFO = YES/NO
<pkg>_REDISTRIBUTE_SOURCE = YES/NO

Of course, if <pkg>_GENERATE_LEGAL_INFO = NO, <pkg>_REDISTRIBUTE_SOURCE
is ignored.

This is just a proposal, I'm totally open to better names for the
variables.

Best regards,

Thomas
