+# Call a custom system command when receiving a hilight.
+# Originally based on hilightwin.pl work and djcraven5's idea for making remote
+# computer beep through ssh.
+#
+# Example of use, assuming you have ssh and beep on your remote:
+#   /set hilightcmd_systemcmd ssh user@host beep &
+#
+# The hilighted text may be passed as a quoted string:
+#   /set hilightcmd_systemcmd printf "%s\n" %(message)s >> ~/hilights
+#
