The Integrations packs for System Center 2012 is here!
Get it here:
there is also the Orchestrator Toolkit (for creating own Integration Packs)
Unfortunately is still contains a bug that prevents you from making a pack that includes a PowerShell library script that gets automatically deployed.
problem is that it put the file in a folder named the same as the GUID of the Integrations Pack, this guid is auto generated, therefore we do not know it prior to compiling the script into the IP.
I have reported this bug at connect, and I am glad to say that it is fixed! We just need to wait for the next release!
