Ok, then I'll add it using the way you described before.

I'm not exactly sure as to how these tests work. From looking at the

That sounds fair. Please contact me at this e-mail address if there  
are any questions regarding the ObjFW support. As long as you don't  
remove it without contacting me, everything is fine by me :).
