Panasync: dependency tracking among file copies

File copying is frequently used to implement ad hoc management of file replicas, backups and versions. Such tasks can be assisted by appropriate applications, at the expense of introducing some restrictions to the usage patterns. In particular, this is the case of interactions involving disconnected machines and transportable media. PANASYNC tries to support these actions by introducing a set of commands for file copying and re-integration that complement the file-system commands and provide support for dependency analysis among time-stamp assisted files.
