Late aims to be a search-based RFC5545 calendar management tool for the command-line.
Initially, there's rudimentary boolean search for calendar events, scanning across calendar files in the file system.
Late's another terrible excuse for being late.
There's basic help via the command-line:
python3 -m late --help- icalendar for parsing calendar data
- lark for parsing queries
