I cheated in all cases : For the optinal LP solvers I don't mind as there is a standard LP solver that exposes the features : http://www.sagemath.org/doc/reference/numerical/index.html For the C libraries solving specfic graph problem there is in every case a method of the Graph class (which appears in the doc). And it either raises an exception when it is called, saying that the package should be installed, or solves the problem in a different way. Whatever you do, add pieces of doc everywhere pointing toward the absent features and explaining how to install them. Nothing better. I would like a way to have the doc appear even in all functions raise an exception, but I don't. If you actually need to inherit from external code, I'm not very optimistic :-/ Nathann -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
