When you install this package, it will automatically register itself with gdb. You do not need to add anything to your ~/.gdbinit file. To use this extension, run your program. If it segfaults/crashes, then type 'exploitable' at the gdb command prompt. It should then print text to the gdb terminal explaining its conclusion. Note that it might misclassify a fault that really is exploitable. So, use this as an informed opinion and not absolute truth. If it says something is exploitable, head this warning just in case. This extension may also be used on coredump files. To use it this way, load the coredump file as normal. Then type 'exploitable' to get the analysis.
