DESCRIPTION
-----------
Libmemcached implements a custom language for configuring and modifying
-servers. By passing in an option string you can generate a memcached_st object
+servers. By passing in an option string you can generate a ``memcached_st`` object
that you can use in your application directly.
-
.. describe:: --SERVER=<servername>:<optional_port>/?<optional_weight>
Provide a servername to be used by the client. Providing a weight will cause weighting to occur with all hosts with each server getting a default weight of 1.
+.. describe:: --SOCKET=\"<filepath>/?<optional_weight>\"
+
+Provide a filepath to a UNIX socket file. Providing a weight will cause weighting to occur with all hosts with each server getting a default weight of 1.
+
.. describe:: --VERIFY-KEY
Verify that keys that are being used fit within the design of the protocol being used.
.. describe:: --REMOVE_FAILED_SERVERS
-Enable the behavior MEMCACHED_BEHAVIOR_REMOVE_FAILED_SERVERS.
+Enable the behavior :c:type:`MEMCACHED_BEHAVIOR_REMOVE_FAILED_SERVERS`.
.. describe:: --BINARY-PROTOCOL
.. describe:: --BUFFER-REQUESTS
-Enable MEMCACHED_BEHAVIOR_BUFFER_REQUESTS.
+Please see :c:type:`MEMCACHED_BEHAVIOR_BUFFER_REQUESTS`.
.. describe:: --CONFIGURE-FILE=
.. describe:: --CONNECT-TIMEOUT=
-Enable MEMCACHED_BEHAVIOR_CONNECT_TIMEOUT.
+Please see :c:type:`MEMCACHED_BEHAVIOR_CONNECT_TIMEOUT`.
.. describe:: --DISTRIBUTION=
Set the hashing alogrthm used for placing keys on servers.
-.. describe:: --HASH-WITH-PREFIX_KEY
-
-.. describe:: --IO-BYTES-WATERMARK=
-
-.. describe:: --IO-KEY-PREFETCH=
+.. describe:: --HASH-WITH-NAMESPACE
-.. describe:: --IO-MSG-WATERMARK=
+When enabled the prefix key will be added to the key when determining which
+server to store the data in.
.. describe:: --NOREPLY
+Enable "no reply" for all calls that support this. It is highly recommended
+that you use this option with the binary protocol only.
+
.. describe:: --NUMBER-OF-REPLICAS=
Set the nummber of servers that keys will be replicated to.
-.. describe:: --POLL-TIMEOUT=
-
.. describe:: --RANDOMIZE-REPLICA-READ
Select randomly the server within the replication pool to read from.
-.. describe:: --RCV-TIMEOUT=
+.. describe:: --SORT-HOSTS
+
+When adding new servers always calculate their distribution based on sorted naming order.
+
+.. describe:: --SUPPORT-CAS
+
+See :manpage:`memcached_behavior_set(3)` for :c:type:`MEMCACHED_BEHAVIOR_SUPPORT_CAS`
+
+.. describe:: --USE-UDP
+
+See :manpage:`memcached_behavior_set(3)` for :c:type:`MEMCACHED_BEHAVIOR_USE_UDP`
+
+.. describe:: --NAMESPACE=
+
+A namespace is a container that provides context for keys, only other
+requests that know the namespace can access these values. This is
+accomplished by prepending the namespace value to all keys.
+
