> but which license apply to this doc set ?

Good question...

Ideally the copyright/License should allow the project to
take the work Paul R. has done and put this into docbook format
if Paul doesn't want to do it himself.

Equally the content should/could be propogated to the Firebird
Wiki, which should be up and running soon - I hope.

Finally the docs should be freely translatable to benefit all.

So perhaps Paul can let us know what we can/can't do with the
work he has done.
