What is the best way to include this file from the runtime libraries?

Hi
I am trying to hook up an app to log to /var/log through the 
rsyslog daemon and
it seems I need this file
https://github.com/dlang/druntime/blob/master/src/core/sys/posix/syslog.d
but I am not sure what the correct way to include files from the 
runtime libs is. Right now I am just doing

import core.sys.posix.syslog;


and that works but I was hoping to get clarified on what is the 
best method for this is?
