+=item B<-m> I<mode>
+
+Set the file permissions of a UNIX domain socket. The option accepts an octal
+number representing the bit pattern for the mode (see L<chmod(1)> for
+details).
+
+Please note that not all systems honor this setting. On Linux, read/write
+permissions are required to connect to a UNIX socket. However, many
+BSD-derived systems ignore permissions for UNIX sockets. See L<unix(7)> for
+details.
+
+This option affects the I<following> UNIX socket addresses (the following
+B<-l> options), i.e., you may specify different settings for different
+sockets.
+
+The default is not to change ownership or permissions of the socket and, thus,
+use the system default.
