Furnel

A command-line utility to compress files using the brotli algorithm. Built because I wanted a simple tool to pre-compress files for a static website.

Why “Furnel”?

The brotli algorithm is named for Brötli, which is the Swiss German word for bread rolls. Bread rolls are baked in an oven, and an oven in Romansh - another Swiss language - is called furnel.

Furnel makes brotli.
