     Written by Stephen Valdinger of Chocolatey Software for Dan Franciscus
+
+    Dependencies work a little funny in how they get stuffed into the object. They come back as an object themselves, so special care must be taken to unroll them.
+
+    e.g.
+    Get-ChocoPackageMetaData -ChocolateyPackage C:\packages\googlechrome.nupkg -AdditionalInformation Dependencies | Select-Object -ExpandProperty Dependencies
