Complete character cfg file relative directories

[Enlil]

Hello,
We are using several complete characters and would like to keep one central repository for the animations. We found that using absolute file positions (ie animation=c:/foo/animation/anim.caf) works, but aren't sure what the convention for relative files is (ie animation=../animation/anim.caf). We tried a couple, but the parser did not recognize. How should the relative directories be referenced?

Thanks,
Christian
