Re: Compile with —enable-coverage

Appreciate the help on this. I think I need to slightly modify the script
to only evaluate my custom .bro / .zeek files. Which seem to be properly
reporting out some lines as being executed.

Before I go down this path, is there some parameter I should pass instead
to only scan my script directory? For example:

/home
    -bro
    -my_scripts
       - - .tmp/script-coverage
