This repository contains a [Go](https://golang.org/) library package that
provides functions to solve, build or validate takuzu puzzles.
- Mercurial repository: https://hg.lilotux.net/golang/mikael/takuzu/
- Github mirror: https://github.com/McKael/takuzu/
Please read the [godoc documentation]](https://godoc.org/github.com/McKael/takuzu) for details.
This project also contains a command line utility, named `gotak`, to solve or
generate puzzles.
I haven't written the tool documentation yet.
This library is used by GotakJS, an [online takuzu puzzle game](https://lilotux.net/~mikael/takuzu/),
written in Go using [GopehJS](https://github.com/gopherjs/gopherjs).
(On mobile, works best with Chrome. On a computer, I've tested it with both Firefox and Chrome.)
