A story file produced with the Inform system belongs to whoever wrote it and may be sold for profit if so desired, without the need for royalty payment, provided that it prints a game banner conforming to the standard library's banner at an early stage in play: in particular, this banner must contain the information that the story file was compiled by Inform, and the version numbers of compiler and library used.
