I saw inside the file like this:
use Apache2:: Module;
use Apache2:: Access;
use Apache2:: ServerRec qw ();
use Apache2:: RequestRec qw ();
use Apache2:: RequestUtil qw ();
use Apache2:: Const qw (: common: override: cmd_how);
use APR:: Pool ();
use APR:: Table ();

# Use Apache2:: Directive qw ();

Nginx is kind of how does the corresponding statement?
