+Takes a list of IPv6 prefixes in conventional format on stdin, and performs two
+optimisations to attempt to reduce the length of the prefix list. The first
+optimisation is to remove any supplied prefixes which are superfluous because
+they are already included in another supplied prefix. The second optimisation
+identifies adjacent prefixes that can be combined under a single, shorter-length
+prefix. The above optimalisation steps are often useful in context of
+compressing firewall rules or BGP prefix-list filters.
