PSFetch is a Powershell take on the popular Linux tools yum & apt-get but for Powershell scripts and addons.

If you are looking for a cmdlet to do a particular task or you know the name and would like to easily get and install it then PSFetch is the tool for you!

psFetch also provides shortcuts and 'friendly names' for the servermanagercmd tool to allow you to add Roles and Features to server 2008 quicker and easier than before!

The cmdlet it is in its final stages of internal Beta testing and I hope to release a public Beta soon!
