seconds and then spawns one (or more) process(es) to synchronize the changes.
By default this is rsync, which must be installed on all source and target
machines.  Lsyncd is thus a light-weight live mirror solution that is
comparatively easy to install not requiring new file systems or block devices
and does not hamper local file system performance.")
