+define Package/aggregate/description
+	takes a list of prefixes in conventional format on stdin, and performs two
+	optimisations to reduce the length of the prefix list. It removes any
+	supplied prefixes which are supurfluous because they are already included in
+	another supplied prefix (e.g., 203.97.2.0/24 would be removed if
+	203.97.0.0/17 was also supplied), and identifies adjacent prefixes that can
+	be combined under a single, shorter-length prefix (e.g., 203.97.2.0/24 and
+	203.97.3.0/24 can be combined into the single prefix 203.97.2.0/23).
