+.
+The \fBmultipathc\fR tool provides an interactive shell for communicating
+with the \fBmultipathd\fR daemon.
+The command \fBmultipathd -k\fR invokes \fBmultipathc\fR.
+.P
+All commands documented in \fBmultipathd(8)\fR are supported.
+The available commands can be viewed by entering '\fIhelp\fR'.
+Use \fIquit\fR, \fIexit\fR, or \fBCTRL-D\fR to exit the shell.
+Keywords can be abbreviated with the first letters (for example,
+\fIshu\fR for \fIshutdown\fR), if the abbreviation is unique.
+Some commands support pretty-printing
+using \fBprintf\fR-style format specifiers. The supported format specifiers
+can be listed with the command \fBshow wildcards\fR.
+Depending on build options, the interactive shell
+may provide command completion and history expansion features.
+.P
+The optional parameter \fBtimeout\fR specifies the timeout to wait for
+a reply from \fBmultipathd\fR, in milliseconds. The default is 4000 ms.

 happens, it will reconfigure the multipath map the path belongs to, so that this
 map regains its maximum performance and redundancy.

 This daemon executes the external \fBmultipath\fR tool when events occur.
 In turn, the multipath tool signals the multipathd daemon when it is done with
