c:\windows\system32\bash.exe 経由で任意のコマンドを手軽に実行できるやつ（要は wslbridge の簡易版）

README.md

Usage:

> $command = "vim"
> rustc -C opt-level=3 -C debuginfo=0 -o "C:\path\to\$($command).exe" wsl.rs
> C:\path\to\vim.exe .\wsl.rs

TODO:

• Windows 側のパスを受け取った場合の対処

wsl.rs

// rustc -C opt-level=3 -C debuginfo=0 -o {command-name}.exe wsl.rs
