[Help-glpk] COIN-OR CGL cut generator library

I wonder if there are any plans for GLPK to provide an interface to the 
COIN-OR CGL cut generator library in order to provide better/deeper cuts 
in MIP optimization?   (CGL is licensed under the CPL which is similar 
to the LGPL)

In my experience the CBC solver form the COIN-OR people, which uses CGL 
library to generate cuts is much faster than GLPK on MIP problems and 
even solves problems GLPK fails to solve.  If you need an example 
problems, I can provide some.

I would prefer to use GLPK for its good support of MathProg and ease of 
use (CBC can only read MPS files and has no modelling support).
