+.SH SYNOPSIS
+.B kamunix
+.BI path_to_socket
+
+.SH DESCRIPTION
+.B kamunix
+is a wrapper for sending external commands
+.B to Kamailio SIP server
+via UNIX sockets interface.

+command along with its paramters (if any) and prints the response 
+to standard output.
+
+.SH PARAMETERS

+.SH EXAMPLES
+.PP
+An Kamailio commands consists in one ore more lines: first contains the
+command name enclosed between ":", the following lines containing the 
+command parameters, one per line.
