A very good ide! BUT: have you seen that, on 
https://projects.coin-or.org/Csdp/ the first links you can see are broken ?




I assume this works on Linux as well - there were some remarks in the
flagmatic user guide that indicated not, but maybe that wasn't because
of CSDP.  I guess I recall that optional packages should work on all
(most?) platforms we support Sage on.

Ok, cool ! Send me a line when you will begin to work on that. And to
Jernej too, whom I added to this email. He may be part of GSOC this
summer, and may want to work on that too.

Could you send an email to sage-devel to ask them "how the hell we are
supposed to libtoolize things without modifying upstream" ? I don't
know either, but I still have scars from the first spkg I put in Sage
and in which I modified upstream : Cliquer :-P

Admittedly it was not a very nice piece of work, though. I mean, what
I did with it of course ! :-D

So, in a way, it already makes sense without anything extra.

Wow. Cool !

Why do you prefer to create 2 tickets for that ? It feels a bit weird to
review an interface between Sage and a spkg which is not included, and it
feels weird to add to Sage a spkg which is not interfaced with it.

Though if the two tickets depend on each other, then no problem ;-)

I had no idea it had evolved into an open source project already :-)

Doing that requires no different work from preparing it to be an
optional package, so why not do that first? Once that's done I would
expect it'll be pretty smooth sailing into optional status.
