I've added another page to the wiki concerning version numbers for packaging: The page ActiveMQ-CPP product version number has been created to specify the way version numbers are used in the project, with some examples. http://cwiki.apache.org/confluence/display/AMQCPP/ActiveMQ-CPP+product+version+number ActiveMQ-CPP, libtool and packaging notes discusses the way version numbers impact libtool and packaging, and make some recommendations for this project. http://cwiki.apache.org/confluence/display/AMQCPP/ActiveMQ-CPP%2C+libtool+and+packaging+notes I don't mean to suggest that this is the `right' way to do things - rather, these pages are just a draft, to get some discussion of the issues.
