One of the Golden Rules of packages is that `leaf' regular packages (like Supercite) may have all their installed files deleted without harm. Individual .el files in single-file packages may be deleted without harm (like lazy-lock.el in the edit-utils package). There's a naming convention to allow Mule packages to coexist with non-Mule XEmacs builds. Put your non-Mule packages in `xemacs-packages' and your Mule packages in `mule-packages'. Any packages in a `mule-packages' hierarchy are left untouched in a non-Mule XEmacs.
