  50 .SH DESCRIPTION
  51 .sp
  52 Libmemcached implements a custom language for configuring and modifying
  53 servers. By passing in an option string you can generate a \fBmemcached_st\fP object
  54 that you can use in your application directly.

  56 .TP
  57 .B \-\-SERVER=<servername>:<optional_port>/?<optional_weight>
  58 .UNINDENT
  59 .sp
  60 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.
  61 .INDENT 0.0
  62 .TP
  63 .B \-\-SOCKET="<filepath>/?<optional_weight>"
  64 .UNINDENT
  65 .sp
  66 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.

  92 .TP
  93 .B \-\-CONFIGURE\-FILE=
  94 .UNINDENT

 162 .UNINDENT
 163 .sp
 164 A namespace is a container that provides context for keys, only other
 165 requests that know the namespace can access these values. This is
 166 accomplished by prepending the namespace value to all keys.
