Merged by lsedlar. Opened by lsedlar.

This command will call rsync to copy selected variants or arches to
another location. Depending on how the filters are set, there may be
more than one call to rsync. There is basic logic to try to minimize the
number of rsync invocations, but there are cases where the job can not
be done with a single call.

There is a dry-run option to check what will happen.
