Goya lets you color the executed methods of the running image.
See the class side of InstrumentingAssociation for examples on how to color methods.
Color some interesting methods and do something with them such that they are indeed executed by the VM.
Then open the GoyaBrowser for browsing only the until now executed methods.
Update the system categories of the GoyaBrowser after you changed something with InstrumentingAssociation.
Never forget to do something with your colored methods!
After (re)compiling methods you currently must redo the coloring with InstrumentingAssociation before the newly compiled method will participate in the coloring.
Goya can handle up to (5 * 5) + 1 = 26 coloring combinations though in the current examples only 2 colors (up to 5 combinations) are used.
After installing the Goya package you must recompile your VM by using VMMaker and the respective tool chain.
