+aggregate (optimise a list of route prefixes)
+
+Takes a list of 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. For example, 203.97.2.0/24 would be removed
+if 203.97.0.0/17 was also supplied. The second optimisation
+identifies adjacent prefixes that can be combined under a single,
+shorter-length prefix. For example, 203.97.2.0/24 and 203.97.3.0/24
+can be combined into the single prefix 203.97.2.0/23.
