Description (last modified by )
This new spkg for Cbc includes several new lines in spkg-install to activate CPLEX support in the Coin Library.
It is to be found at : ~ncohen/cbc-2.3.p2.spkg
This functionality can be used with the corresponding patch #8172

Since this is new, you need to state whether it is intended to go into experimental or optional. Also, since this is new, you should remove the .p2 from the spkg name and instead call it cbc-2.3.spkg.
If you update this, before it is committed to Sage, just replace it, or provide a new link. The patch number increments each time a new version is added to Sage - not each time you change your version.

Sorry, there is some confusion here.

The package is intended for optional, because that's where CBC is right now.
Also, since this is new, you should remove the .p2 from the spkg name and instead call it cbc-2.3.spkg.
As hinted above the SPKG is indeed not new but an update. The CPLEX support in the ticket #8172 is new but *this* ticket only updates the CBC SPKG to work with the new interface. A true update. There is and never will be a CPLEX SPKG because CPLEX is proprietary.
Hope that clarifies the situation somewhat.

Yes, it does clarify this. I was under the impression this was a new package, rather than an update to a pre-existing one.
I've stuck it back to needs review. I'm personally unable to review it, as it is outside my level of expertese.

Harald, can you take a look at the SPKG? I tried it and it works but someone needs to check for the basics (hg status, SPKG.txt, etc.) and I'm busy for the next few days.

Finally ..... This package has been tested on t2 (Solaris). It compiles and runs ! :-)
As soon as this and #8172 are in Sage, it will be possible to work on the inclusion of SCIP !
