    11== Introduction ==
    2 A large part of the game like components, GUI scripts or the AI are written in Javascript. If you have programmed C++ or used Javascript for Websites you probably know how important a good Debugger can be and how much it helps to find Bugs or learn how a Part of code works.
    3 The web based Tools like Firebug can't be used for 0 A.D. because the debugger has to be very closely connected to the Javascript runtime. However, there's a dedicated tool for 0 A.D. and the Pyrogenesis engine being developed at the moment that should hopefully be ready to use soon.

    55== Technical background ==
    6 The DebuggingServer component makes debugging commands like (ToggleBreakpoint, Step, Continue etc...) available using a mongoose webserver.
    7 The format used for return values is JSON, which should be easy to parse from a Web-GUI.

    9 The Debugger uses the JSDBGAPI provided by Spidermonkey 1.8.5. Newer versions of Spidermonkey provide a simplified new API (along with memory leak fixes, performance improvements and more), but unfortunately Mozilla isn't interested in doing the work and publishing a independent build from Firefox at the moment.
