+LP schedule iCal export
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The ``--ical`` switch enables iCal export while generating LP
+schedule::
+
+  $ lps_gen -s --ical 2016 path/to/lp-schedule.jinja2 path/to/lp-schedule.md > path/to/program-schedule.html
+
+The year of the conference must be given as an argument to the
+``--ical`` switch.
