futureEvents.n3: an excercise in processing recurring events

I got a new WearableGizmo. I was using evolution.
I need to know: what events from my evolution calendar need
to be in the WearableGizmo in order
for it to do its jobs of (a) beep when
I need to do something, and (b) don't let me
schedule two things at the same time?

clearly past events don't matter.

So I wrote this thingy to find events in the future.

The <,evocal.rdf> reference refers to the output of
  http://www.w3.org/2000/10/swap/pim/ical2rdf.pl
here's the makefile stanza:

,evocal.rdf: $(HOME)/evolution/local/Calendar/calendar.ics ical2rdf.pl
	$(PERL) ical2rdf.pl --xnames $(EVONS)
$(HOME)/evolution/local/Calendar/calendar.ics >$@

note: this uses YYYYMMDD for dates, but I intend
to enhance ical2rdf.pl to convert to YYYY-MM-DD form
presently.
