The PowerShell provider for BizTalk lets you manage BizTalk artifacts from within the PowerShell console.
History:
In july 2008 I got the idea to build a PowerShell provider for BizTalk. During the months after that I made a design and started coding (in my free time 
). I blogged about the provider for first time in October 2008. In January 2009 I released the first alpha version. While working on the next release I was contacted by Maxime Labelle who also started building a provider for BizTalk. We decided to merge the two projects and that is where we are now. The joined effort is hosted on codeplex.
