-OPTIONS
+Options
 -------
-<CAPACITY>
+
+.. option:: <CAPACITY>
+
     Maximum number of Data packets the CS can store.
     Lowering the capacity causes the CS to evict excess Data packets.
 
-admit on|off
+.. option:: admit on|off
+
     Whether the CS can admit new Data.
 
-serve on|off
+.. option:: serve on|off
+
     Whether the CS can satisfy incoming Interests using cached Data.
     Turning this off causes all CS lookups to miss.
 
-<PREFIX>
+.. option:: <PREFIX>
+
     Name prefix of cached Data packets.
 
-<COUNT>
+.. option:: <COUNT>
+
     Maximum number of cached Data packets to erase.
     The default is "no limit".
