NAME

overview - Project overview The QuantLib project is at this time in beta status.

The following list is a (possibly outdated) overview of the existing code base.

The QuantLib-users and QuantLib-dev mailing lists are the preferred forum for proposals, suggestions and contributions regarding the future development of the library.
