 NautyGraphs.jl is a Julia interface to [_nauty_](https://pallini.di.uniroma1.it/) by Brendan McKay. It allows for efficient isomorphism checking, canonical labeling, and hashing of vertex-labeled graphs. In addition, NautyGraphs.jl is fully compatible with the [Graphs.jl](https://github.com/JuliaGraphs/Graphs.jl) API. This makes it easy to create or modify graphs through familiar syntax, and allows NautyGraphs to work with a large library of graph algorithms.
-**Warning**: NautyGraph.jl currently does not work on Windows. This will be hopefully be fixed soon.
