This new tool released as an open source project on Codeplex enables you to easily author Powershell CMDLets including context based help.

During the development of Windows 7, most cmdlet design and help authoring in Microsoft went through an internal tool called the “Cmdlet Designer.”

The Cmdlet Designer makes it much easier for teams to concentrate on the design, naming, and consistency of their cmdlets, while also guaranteeing name registration and collision avoidance across Microsoft.

To sweeten the deal, it offers:

• Integrated help authoring
• Efficient bulk operations (parameter and cmdlet cloning)
• Generation of cmdlet code
• Full scripting support
• Automatic code-spec comparison and testing
• Role-based security, history logging, and more.
