PowerShell Community Extensions 1.0 Released @ CodePlex
Keith Hill released the PowerShell Community Extensions version 1.0 at http://www.codeplex.com/PowerShellCX. This well documented set of extra CmdLets, aliases and scripts provides you with a lot of goodies that make life in both PowerShell as a Shell and PowerShell as a scripting language way easier.
One of the nice goodies is the Get-CmdletMaml cmdlet which reflects over a snapin assembly and produces PowerShell MAML help. It uses a number of attributes defined by PowerShell and .NET as well as some defined by PSCX. Maml is an XML format to describe help on PowerShell cmdlets and their arguments.
It also contains the latest version of TabExpansion functionality I wrote about in this blog post.
See the Documentation for details on all the new commands. Check this out if you live your life in PowerShell.
And by the way: CodePlex provides source code to the goodies, so there is a lot of code here to learn from how to do PowerShell development!
