Re: Is anyone planning to pick up the orphaned coin-or-* packages?

I seen this problem some days ago and taken them because some coin-or* 
are packages needed by openms.

Any other coin-or packages still unmaintained but important?

I just wanted to draw attention to the orphaned coin-or-* packages,

linear, nonlinear, and integer programming. I’m curious if anyone is 
planning to pick them up or if they are truly at risk of retirement. 
Several interesting packages depend on these, and it would be a shame to 
lose the whole collection.

In principle, I might consider picking up at least some of these 
packages, but they aren’t quite trivial, and I haven’t had time to look 
at them closely. I don’t have a lot of spare cycles right now, and I 
don’t like taking ownership of packages without doing a really detailed 
review, cleaning up anything that’s outdated, and fully understanding 
what I’m getting into.

The following packages that depend directly on at least one coin-or-* 
package appear to be leaves:

     freefem++, mp, openms, python-cyipopt

The following are not leaves:

     opencv – the coin-or-Clp dependency appears to be removable with 
some loss of functionality

     python-pulp - needed for the whole Snakemake stack, requires coin- 
or-Cbc

     scip - needed for Macaulay2, mp, papilo, and polymake, the latter 
two of which are not leaves

     spasm - needed for Singular, which is not a leaf
