The (=10) is meant to give default value. The only problem I've found is that we need to specify empty default value string for std::vector, which leads to code like this:
("second", value< vector<int > >()->default_value(vector<int>(1, 1), ""))
Ok, maybe we just need 'vector_value' function which will take care of default values.
The default value could simply be given as a string in that case: "(1,1)" or whatever. You could also use the OutputFormatters library when it is accepted into Boost. (In that case, you just wait for your automated solution.) -- Rob Stewart stewart@sig.com Software Engineer http://www.sig.com Susquehanna International Group, LLP using std::disclaimer;
