Ruby Version Manager 4 Windows v1.0.0 released

The final version 1.0.0 of the Ruby Version Manager for Windows (rvm-windows) has been released. It is inspired by the rvm.io project for Unix systems and provides a similar user experience for Windows users by providing a compatible command line interface. The Ruby Version Manager for Windows is a command line tool that allows you to easily install, manage, and work with multiple Ruby environments from interpreters to sets of gems. It even works with the classic Windows command line aside from Powershell and is based on the x64 binaries provided by the RubyInstaller project. Its goal is not to 100% reimplement all features of rvm.io, but the most important and common ones by preserving most of the same command line interface. Some special Windows related stuff is added as well. More information can be found on the rvm-windows Github repository.
