# ccc
`ccc` is a rewrite of [fff](https://github.com/piotr-marendowski/fff) in C aiming for [sucklessness](https://suckless.org/philosophy/) and speed.
`ccc` is a rewrite of [fff](https://github.com/piotr-marendowski/fff) in C aiming for usefulness and speed.
The fact that it is written in C makes it more versatile and rapid, enabling us to add features that were previously ruled out due to time complexity. You may call it a `soft fork`.
## Features
Consider this project incomplete and WIP!
