Updated for Leopard (Mac OS 10.5). Will still work in Tiger (10.4).
Option to enable checksums: Previous versions of Duover used checksums to compare files before copying. This is now disabled by default as it slows down network syncs without providing much benefit, and has been known to cause issues when syncing with Windows volumes (FAT or SMB shares). Advanced users may enable on a per-configuration basis in Options.
