11This license establishes the terms under which a given free software
12Package may be copied, modified, distributed, and/or redistributed.  The

15available as open source and free software.

17You are always permitted to make arrangements wholly outside of this
18license directly with the Copyright Holder of a given Package.  If the
19terms of this license do not permit the full use that you propose to
20make of the Package, you should contact the Copyright Holder and seek a
21different licensing arrangement.

115apply to the copy that the licensee received, and requires that the
116Source form of the Modified Version, and of any works derived from it,
