This is the Debian GNU/Linux prepacked version of the octave-sp package. It
is based on semidef-oct which is itself a port to Octave by A. S. Hodel
<a.s.hodel@eng.auburn.edu> of the semidef package by Lieven Vandenberghe
<vandenbe@esat.kuleuven.ac.be> and Stephen Boyd <boyd@isl.stanford.edu>.
This package was put together by Dirk Eddelbuettel <edd@debian.org> from the
sources at
ftp://ftp.eng.auburn.edu/pub/hodel/semidef-oct.tar.gz
Also included were two Octave script files (run_cmd.m, prompt.m) from his
OCST package that is available as
ftp://ftp.eng.auburn.edu/pub/hodel/OCST-980904.tar.gz
Some minor changes were made which are documented in the file
/usr/share/doc/octave-sp/changelog.Debian.gz.
This package is curently maintained by the Debian Octave Group
(http://pkg-octave.alioth.debian.org).
The semidef package contains the following statement in the file COPYRIGHT
and in the src/*.c files:
Copyright (c) 1994 by Lieven Vandenberghe and Stephen Boyd.
Permission to use, copy, modify, and distribute this software for
any purpose without fee is hereby granted, provided that this entire
notice is included in all copies of any software which is or includes

supporting documentation for such software.
This software is being provided "as is", without any express or
implied warranty. In particular, the authors do not make any
representation or warranty of any kind concerning the merchantability
of this software or its fitness for any particular purpose.
This statement is ambiguous as regards DFSG-compliance of the package. We
contacted the upstream authors to obtain a clarification of the license
terms [1]. They agreed to switch the license to the Lesser General Public
License (LGPL) [2][3]:
* Lieven Vandenberghe <vandenbe@ee.ucla.edu> [2007-08-06 09:13]:
> I can see why our license is ambiguous. When we wrote it in 1994, we
> intended it to mean that the program is entirely free, for any purpose
> (including commercial) and without any restriction.
>
> If it is easier if we switch to a standard free license, I would choose
> the LGPL.
* Stephen Boyd <boyd@stanford.edu> [2007-08-06 12:50]:
> whatever is easiest. i am happy with semidef_prog having either license.
