JetBrains has graciously donated a license of PHPStorm, a PHP integrated development environment, to the Manx project. JetBrains supported open source projects like Manx with free licenses to their product. Thanks, JetBrains!

I’ve used other JetBrains products before, such as ReSharper, a productivity add-on for C# development in Visual Studio, and IntelliJ Idea, a Java development environment. I recommend both of these products highly!
