Hi all,  

is there a way to @load a script in bro only if the file exists?  

My scenario is that I'd like to be able to include configuration data  
from, e.g., /etc/bro-config.bro. But this script might not exist in all  
scenarios. Loading it via @load gives an error if the file doesn't exist.  

I've tried to use @prefixes to conditionally load scripts, but couldn't  
figure out exactly where bro would be searching for those scripts.  

If there an equivalent for something like "if [-f /etc/bro-config.bro] " ?  

Best regards,  

Dirk
