Traipse Dev 'OpenRPG' {090818-00} Traipse is a distribution of OpenRPG that is designed to be easy to setup and go. Traipse also makes it easy for developers to work on code without fear of sacrifice. 'Ornery-Orc' continues the trend of 'Grumpy' and adds fixes to the code. 'Ornery-Orc''s main goal is to offer more advanced features and enhance the productivity of the user. Update Summary: *Unstable* This is the first wave of Code Refinement updates. Includes new material from Core Beta; new debugger material (partially implemented), beginnings of switch to etree, TerminalWriter, and a little more. open_rpg has been renamed to component; functioning now as component.get(), component.add(), component.delete(). This version has known bugs, specifically with the gametree and nodes. I think the XML files where not removed during testing of Core and switching back.
