Hey unix nerds. Probably like a decade and a half ago on linux I had a console calendar program sorta like cal, but you could store oneoff or repeating events in a text config file. With the right options you could get a cal-style month, or you could get a list of events for the day or week.

Any guess what it was? Web searches are useless now that shitty content farms have taken over and there's a million sites trying to teach me to use cal or some x program.
