+- update to version 20180309:
+ * sc_*:
+  * For the utilities (sc_*) that read input files, do not allocate
+    memory to hold the entire input file in memory before parsing
+    the file.  This improvement affects sc_ally, sc_attach,
+    sc_bdrmap, sc_filterpolicy, sc_radargun, sc_speedtrap,
+    sc_tbitblind, sc_tbitpmtud, sc_uptime, sc_warts2text.
+ * sc_tbitpmtud:
+  * add scamper driver from IMC2010 paper to collect data on webserver
+    responsiveness to ICMP packet too big messages, and perform
+    rudimentary analysis of collected data.
+ * sc_ttlexp:
+  * new utility to dump source addresses from ICMP TTL expired
+    messages in warts files.
+ * sc_wartsfix:
+  * add a manual page
+ * sc_warts2csv:
+  * add a manual page
