Broot uses [syntect](https://crates.io/crates/syntect) for syntax highlighting in text files.
This (excellent) library needs Sublime Text syntax definitions for all languages (when a language definition isn't found, Broot displays the text monochrome).
Syntect doesn't come with an extensive set of definitions.
The [bat](https://github.com/sharkdp/bat) project maintains with care an important list of such definitions (most as submodules, some with patches).
It's the best public list I found, so I've included the resulting syntax set here as `syntaxes.bin`.
You may replace this file with your own, building it with Syntect's [`syntect::dumps::dump_to_uncompressed_file`](https://docs.rs/syntect/latest/syntect/dumps/fn.dump_to_uncompressed_file.html) function.
