Hi Franz,

as far as I know there are not that high demands for 'creativity' as you
may think. To drive the case into a very extrem example:

The words in a text are common property. Therefore there is no need for
you to pay a fee for using the words 'a' or 'the'. But this does not give
you the right to copy any printed book even when only using words you can
find in an ecyclopedia.

Therefore it would be dangerous to copy files from sources which have not
been declared to be free, when also copying the date of being changed the
last time or when being created.

As I told, I am not an expert, but the theme is a little bit more complex.

Regards, Reinhard.
