Re: Specifying a debuginfo path independently of sysroot

I guess the first question is why would one want to do this ?..maybe 
there is a larger problem that we should fix, also for the record :)

If you do go for it here are a couple of things to look out for:

1) I think CommandLineParser.java would be a good spot to add it so that 
the functionality tricles down to all the command line utilities.

2) We are currently in a slow switch from CNI to JNI so we have two sets 
of bindings that we are maintaining. So if you do touch the bindings 
make sure you update the JNI side of things... hopefully this would be 
over by frysk 0.5 :)

3) It would be really cool if your patch comes with a test case. The 
frysk test suite is nice to work with now-a-days. You can find examples 
in Test*.java... then copy/paste and edit.

Cheers,
