[phenixbb] ligand problem in phenix.refine

Hi, I want to run phenix.refine on a glycoprotein, but the sugars are not in the standard library. I just wonder whether there is a refmac-style syntax (LIBIN) in phenix.refine to include a user-written ligand library, instead of adding and modifying the existing phenix library. Thanks!
