Just made V2.0.0 available.
This version has fancy expression filters e.g:
Code:
ofexport -E -a done=any -I -t "flagged or (due='to tomorrow')" -o /tmp/ex8-due-or-flagged.taskpaper
creates a taskpaper document with all uncompleted tasks that are flagged or due in the next 2 days.
Usage examples
here.
Full documentation

I've been using this version for about a week so most of the screamingly obvious bugs are gone but the expression parsing is pretty new so bear that in mind...
