 .DESCRIPTION
 This script searches for all available Visual Studio Solutions (.sln files) and attempts to run MSBuild to build them for the specified configurations and platforms.
 
+.PARAMETER Samples
+A regular expression matching the samples to be built.  Default is '' that matches all samples.  Examples include '^tools.' or '.dchu'.
+
 .PARAMETER Configurations
-A list of configurations to build samples under. Values available are "Debug" and "Release". By default, $env:Configuration will be used as the sole configuration to build for. If this value doesn't exist, "Debug" will be used instead.
