Sasso is a compiler for Sass, the Syntactically Awesome Style Sheets
language, written in Rust. Sass provides features such as variables,
nesting, mixins, inheritance and imports, which allows one to write
CSS (Cascading Style Sheets) more easily and tersely.

Sasso supports both the SCSS syntax -- a superset of CSS3 -- and the
older indended Sass syntax. It aims for a perfect compatibility with
the current release of Dart Sass, the reference implementation of the
Sass language. It is tested against the official Sass Spec Suite where
it achieves a 100% success rate on the subset implemented by Dart
Sass, producing byte-for-byte identical outputs.
