 ## Rainbow output (lolcat)
 
-`zsh/lolcat.zsh` wires lolcat into a few shell helpers. Works with either build:
-Debian's [busyloop/lolcat](https://github.com/busyloop/lolcat) (Ruby,
-`/usr/games/lolcat`) or the faster [jaseg/lolcat](https://github.com/jaseg/lolcat)
-(C) when built and placed ahead on PATH (`/usr/local/bin/lolcat`). Both auto-detect
-a tty — they colorize straight to the terminal but pass text through plain when
-piped onward, so use `-f`/`--force` to colorize mid-pipeline.
