  46 .SH DESCRIPTION
  47 .sp
  48 Libmemcached implements a custom language for configuring and modifying
  49 servers. By passing in an option string you can generate a \fBmemcached_st\fP object
  50 that you can use in your application directly.
  51 .INDENT 0.0
  52 .TP
  53 .B \-\-SERVER=<servername>:<optional_port>/?<optional_weight>
  54 .UNINDENT
  55 .sp
  56 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.
  57 .INDENT 0.0
  58 .TP
  59 .B \-\-SOCKET=<filepath>/?<optional_weight>
  60 .UNINDENT
  61 .sp
  62 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.
  63 .INDENT 0.0

  88 .TP
  89 .B \-\-CONFIGURE\-FILE=
  90 .UNINDENT
  91 .sp
  92 Provide a configuration file to be used to load requests. Beware that by using a configuration file libmemcached will reset memcached_st based on information only contained in the file.

 120 .B \-\-NOREPLY
 121 .UNINDENT
 122 .sp
 123 Enable "no reply" for all calls that support this. It is highly recommended
 124 that you use this option with the binary protocol only.

 158 .UNINDENT
 159 .sp
 160 A namespace is a container that provides context for keys, only other
 161 requests that know the namespace can access these values. This is
 162 accomplished by prepending the namespace value to all keys.
