[Clp] Is the project still maintained?

[Haroldo Gambini Santos]

Not only actively supported but it is much faster than other open source 
LP solvers (i.e. several times faster and more stable than GLPK or 
LPSolve).

This is one big difference from GLPK, for example, GLPK has a great 
documentation, but lacks performance and stability in my experience.

Cheers,
