Why?
I run relatively slow hardware and I'm travelling in Bali, Indonesia at the moment. Loading lemmyverse.net in a web browser takes ages and gets the laptop fans spinning (it's hot here!). So I had some fun creating a tiny command-line program to find Lemmy communities using classic UNIX tools awk(1), tr(1), grep(1) etc.

transformed, then stored in the user cache directory. To regenerate the
database, remove the file and run lemmyverse again.
