[Help-glpk] GLPK output problem

[Nicolo Giorgetti]

Dear all,

I received this comment for the glpkmex, a Matlab MEX interface for
glpk, but I think it may be of interest not only for Matlab users:

I was wondering if the output of show_progress(tree) should be redirected with
lib_set_print_hook as any other output printed by glpk. If this is not
possible I would like to know why.
