Support running on Windows

[Bouke]

This tool looks like something that could be useful to me. I'm mostly developing on my Mac, however the build runs on Windows (VM). I'd like to mirror two folders, as the virtual network share just is too damn slow.

I can't get it to startup, and I'm unsure where to take it from here. watchman.exe is in the same folder as where I'm running this command from.

Hi @Bouke, yeah unfortunately I've only personally needed to support Linux and so haven't investigated Windows support. I'd be happy to accept PRs though!

I'm not windows user, but did you tried wsl (maybe with docker image) to run mirror?

[stephenh]

@Bessonov that's interesting, but no I haven't tried that. I don't have any Windows machines available and could probably find a virtualbox / something to run, but haven't really been that curious about it.

Just to confirm, WSL works. The performance is not as good as with running it on Windows, but once the initial sync is done it is more than fast enough.
