Given a list of calendars (in icalendar format), output all events within a given timeframe to org format.
Written as an alternative to ical2org.py, as I needed something that would handle calendars from multiple sources and had a stable sort (re-running the program on the same inputs will give the same ordering).
A nix derivation is given in build.nix.
Print out all events within the last two days and the next week:
./ov2o.exe /path/to/my-calendars/ 2 7
