+\n\
+ACTIONS\n\
+ -L|--list-all-sections List all sections\n\
+ -l|--list-sections <prefix> List sections with the given prefix\n\
+ --filter-key <key> Filter section list to only include sections\n\
+ with given key defined.\n\
+ --filter-key-value <key>=<val> Filter section list to only include sections\n\
+ with given key/value pair.\n\
+ --lookup <key> Print a configuration setting to stdout.\n\
+ Returns 0 (success) if the configuration setting is\n\
+ found; 1 otherwise.\n\
+ -r|--resolve-search search for the first file that exists and\n\
+ can be opened in the resulted comma\n\
+ delimited search list.\n\
+\n\
+FLAGS\n\
+ --name name Set type.id\n\
+ [-s <section>] Add to list of sections to search\n\
+\n\
+If there is no action given, the action will default to --lookup.\n\
+\n\
+EXAMPLES\n\
+$ ceph-conf --name mon.0 -c /etc/ceph/ceph.conf 'mon addr'\n\
+Find out what the value of 'mon addr' is for monitor 0.\n\
+\n\
+$ ceph-conf -l mon\n\
+List sections beginning with 'mon'.\n\
+\n\
