This Debian package contains the parts of GNU Guile that cannot go into Debian main because their licenses do not satisfy the Debian Free Software Guidelines (DFSG). The original upstream source was downloaded from ftp.gnu.org/pub/guile. Most of Guile is covered under the terms of the LGPL. See the file /usr/share/common-licenses/LGPL for more information. However, this package contains files which were deemed unsuitable for Debian main because their licenses do not appear to satisfy the requirements of the Debian Free Software Guidelines (DFSG). See http://www.debian.org/social_contract. In particular, the info pages included in this package are covered under the GNU Free Documentation License, which Debian has decided does not satisfy the DFSG in cases where "Invariant Sections" are specified (this includes front and back cover texts). See this Debian General Resolution on the topic: http://www.debian.org/vote/2006/vote_001. Some other files are included here because their license only allows verbatim copying, or there was some other question. See the "GNU Free Documentation License" node in the Guile Reference manual ("info guile-1.8") for the full text of the GFDL.
