+    Runs the Challenge Mode random enemy generation algorithm on the input map\n\
+    file, looking for the seed that results in the fewest extra events and the\n\
+    fewest enemies overall, optionally restricting to specific enemy types. A\n\
+    version option is required. The --minimize=TYPE option may be used\n\
+    (possibly multiple times) to specify enemies that are undesirable in the\n\
+    resulting map, and the optimizer will try to minimize occurrences of those\n\
+    enemies. TYPE should be specified as an integer (for example, 0x0040 for\n\
+    Hildebears; see Map.cc for a full listing). Event count always takes\n\
+    precedence; that is, a map with fewer events is always considered better\n\
+    than any map with more events, regardless of the enemy counts. The\n\
+    --threads=NUM-THREADS option may be used to limit parallelism; by default,\n\
