Adam,
 
Yes, you have my permission to include ParMetis's source and binary
distributions on Debian's mirror
sites.
 
George

Hello,

Thank you again for granting permission to upload ParMETIS into Debian.
I successfully built packages and uploaded them, but they were rejected
by the archive manager, because we need to make certain of your approval
for one thing not mentioned in my original message:

Do you approve of the posting of ParMETIS source and binary packages on
the 800+ Debian mirror servers around the world, as a means of delivery
to our users?

Also, I made an error in my original message: because of its non-free
status, my ParMETIS packages will not be automatically built for the
eleven processor architectures mentioned.  I personally have the
facilities to build packages for the IA-32, Alpha, PowerPC and ARM
architectures, and plan to do so; when a Debian release approaches, I
might also use some of the project's machines to built the final release
binary packages for other popular computing architectures such as IA-64
(Itanium), Sparc, HP PA-RISC and S/390.  And the package source will be
available for people to build their own packages on whatever
architecture they please.

Again, thank you, and I will keep you informed of the package's
progress.

Adam,
 
Sure, go ahead and include ParMetis in Debian. There are a couple
outstanding bugs with the
current release of ParMetis that I will be fixing soon, but the changes
will be minimal.

Subject: Distributing ParMETIS with Debian


Greetings,

I am writing to request your permission to distribute ParMETIS with
Debian GNU/Linux.  Debian (http://www.debian.org/) is an all-volunteer
distribution of the Linux kernel with thousands of accompanying software
packages, similar to but much larger than RedHat, SuSE, Mandrake,
Lindows, etc. (in fact, Lindows is based on Debian's free packages).  I
am one of the ~850 volunteer maintainers of Debian; I maintain the PETSc
<http://www-unix.mcs.anl.gov/petsc/>  and Babel
<http://www.llnl.gov/CASC/components/babel.html>  packages among others.
Because PETSc can link to ParMETIS, I would like to be able to include
it in the Debian distribution.

[I am aware of the work of Eray Ozkural to package METIS for Debian, as
I was his mentor and sponsor when he was doing that work as part of the
process of becoming a Debian maintainer.  Unfortunately, for various
reasons his application to become a maintainer was rejected, and his
packages including METIS removed.  This will thus be a new packaging
effort by an already-approved maintainer.]

Debian packages are grouped according to the "freedom" of software
licenses.  Since the ParMETIS license is not "free" by Debian standards
(http://www.debian.org/intro/free ; basically the same as the Open
Source  <http://www.opensource.org/docs/definition.php> Definition), it
would go ino the "non-free" section of Debian, which would alert
potential users that copying and usage are restricted, so they should
check the copyright file for such terms.  (The other two sections are
"main", consisting entirely of free software, and "contrib", consisting
of free software which depends on non-free software, e.g. when PETSc
linking to ParMETIS is uploaded, its dependency on non-free ParMETIS
will require moving it into contrib.)  In every ParMETIS package (static
libs, shared libs, documentation, etc.), your copyright conditions would
appear as the file /usr/share/doc/parmetis*/copyright , and users would
be bound by those terms just as if they downloaded ParMETIS from your
website.

When/if I receive your permission, I will upload into the Debian archive
the pristine ParMETIS source tarball, together with a gzipped patch
containing the Debian packaging, and a third small file with MD5
checksums of the first two and a list of Debian packages required to
build ParMETIS binaries; this third file will be GPG-signed by me to
guarantee the integrity of all three files.  I would thus become the
"Debian maintainer" of the ParMETIS package, in the same way as I am the
maintainer of packages for PETSc, Babel, Surface Evolver, and installers
for the Compaq Alpha Linux compilers.  With your permission, I would
like to make some small changes, such as building a shared ParMETIS
library, and fixing any bugs I might find.  I will inform you in advance
of any such changes, and you will be able to exercise as much or as
little control over these changes as you like.

The Debian packaging mentioned above consists of a set of scripts and
definition files for the building of binary Debian packages based on the
source code.  Taken together, these files serve a similar purpose to the
spec file for creating RedHat .rpm packages, but with considerably more
flexibility.  The binary Debian packages will then be built by
autobuilder machines for all of the target architectures, which
currently include: IA-32, IA-64, Alpha, Sparc, PowerPC, M68K (yes, there
are still a bunch of Amiga users around :-), MIPS (big- and
little-endian), ARM, S/390 and PA-RISC; support for Hitachi SuperH and
alternate kernels on some of these architectures is in the works.

This packaging will make ParMETIS and packages which depend on it
considerably easier to use, by allowing users to download, say, a
parallel fluid dynamics package named "fluids" by typing "apt-get
install fluids", which would download and install fluids, the ParMETIS
library, and all other support libraries required to run fluids.  Users
(who run Debian) will not need to compile or link anything, this work
will all be done in advance.

If you (and the University of Minnesota) agree to the above, I will
begin working on the Debian packaging for ParMETIS, and when that
packaging is complete, will inform you and upload it into Debian.  This
will place ParMETIS in the "unstable" distribution immediately, and when
it meets several criteria (no build failures on any architecture, no
bugs of severity serious or higher, 10 days since upload into unstable),
it will be moved into the "testing" distribution.  If the package is in
the "testing" distribution when a release is made, it will be included
in that "stable" distribution release.

Independent of your decision regarding Debian, I would like to request
that you (U.Mn. etc.) make the METIS family available under a free/open
source license of some kind.  For example, the Babel SIDL compiler is
released under the GNU Lesser General Public license, which among other
things, eliminates the need for this sort of permission request for
Debian redistribution (though I am in frequent contact with Babel's
authors, and consulted them before my initial upload), and also allows
me to patch it in various ways important to my users.  In your case, you
might be more interested in the GNU General Public License, which would
not allow linking into proprietary software packages.  (As the copyright
holder, you could also license *METIS to companies under separate
conditions.)  As another example, I have simplified linking of the PETSc
libraries with C++ code without the extra disk space and build time
required by the authors' C++ scheme, and patched a problem in PETSc's
timestepping code; both of those patches were sent to the PETSc authors.
Thus open source licensing adds value to PETSc, as it does for such
well-known software as Linux, Apache, Mozilla, GNOME, OpenOffice,
autoconf/automake/libtool, etc., and could do the same for ParMETIS.

Thank you for your time and attention.  I hope that you will approve of
my request to package and distribute ParMETIS with Debian, and that you
will give serious consideration to open source licensing of ParMETIS.

Sincerely,

--
