+        .SYNOPSIS
+            Get parameter values from PSBoundParameters + DefaultValues and optionally, a configuration file
+        .DESCRIPTION
+            This function gives command authors an easy way to combine default parameter values and actual arguments.
+            It also supports user-specified default parameter values loaded from a configuration file.
+
+            It returns a hashtable (like PSBoundParameters) which combines these parameter defaults with parameter values passed by the caller.
