-USAGE\n\
-ceph-conf <flags> <action>\n\
-\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\
-RETURN CODE\n\
-Return code will be 0 on success; error code otherwise.\n\
