Guile-Cairo's documentation is largely derived from Cairo's
documentation, which like Cairo's source code is dual-licensed, under
the LGPL version 2.1 and the MPL version 1.1.

Cairo's documentation is Copyright 2002-2011 Carl Worth and others.

Guile-Cairo's modifications to the Cairo documentation are also licensed
under those terms, to facilitate contribution to upstream docs.

Guile-Cairo's modifications to that documentation are
Copyright 2007,2011 Andy Wingo.

Guile-Cairo does allow online access to that documentation, via the
`help' facility (through cairo-procedures.txt), but since this is not
normally loaded, and it is equivalent to accessing an info page, we do
not consider such access as forming a work based on the Cairo
documentation.
