MSYS2 is a modern rewrite of MSYS, both of which are Cygwin (POSIX compatibility layer) forks with the aim of better interoperability with native Windows software. It aims to provide support to facilitate using the bash shell, Autotools, revision control systems and the like for building native Windows applications using MinGW-w64 toolchains. It comes with a port of ArchLinux's Pacman package manager. Three repos are provided with over 1000 packages.
