When I visit http://docs.nuget.org/docs/reference/package-manager-console-powershell-reference i'm not seeing an option to list installed packages for a given project using pmc command.  Does one exist or is using the <project> | manage nuget packages | installed GUI and <project>\pacakages.config the only way to see that info?

if you provide the -ProjectName parameter to the Get-Package command, it will only list installed packages for that project.

excellent, thanks for the details.
