summary: >
lolcat-c is a small, high-performance re-implementation of the
`lolcat <https://github.com/busyloop/lolcat>`__
rainbow cat utility. lolcat-c is meant as a lolcat that you can actually use in production. It is fast, not slowing
down whatever you pipe through it, and it robustly handles real-world terminal output including escape sequences.
