Function Details

swap_dir(src_dir, dst_dir, keep_old=False, backup_ext=`'.tmp'`)

Rename src_dir to dst_dir. The dst_dir is first renamed to dst_dir + backup_ext to keep the interruption short. Then the src_dir is renamed. If keep_old is False, the old content of dst_dir will be removed.

_force_rename_dir(src_dir, dst_dir)

Rename src_dir to dst_dir. If dst_dir exists, it will be removed.
