Thanks for your prompt reply.  I appreciate your efforts for clarifying the
license terms of semidef_prog, together with .

I suspected that semidef_prog was already an old albeit working software.  I
do not use optimization software very frequently and my interest is to
insure that the octave-sp package (derived from semidef_prog) will not
disappear from Debian.  Note that the number of users who already installed
the package is non-negligible [1].

As regards your proposal to get your more recent software ported to Octave,
I think it is a great idea.  The 2.9.* series of Octave has a improved
Matlab compatibility level, so the chances your packages will run on Octave
are increased.  Moreover there is already a group of developers of the
Octave-Forge project [2] working on optimization. They might be interested
in including your new software in their package [3].

At any rate, the more urgent thing to do is to clarify the semidef_prog
license terms, such that the package can be kept in Debian.
