#  Intel Binary Product Data Generation Tool (Intel BPDG).
#  This tool provide a simple process for the creation of a binary file containing read-only 
#  configuration data for EDK II platforms that contain Dynamic and DynamicEx PCDs described 
#  in VPD sections. It also provide an option for specifying an alternate name for a mapping 
#  file of PCD layout for use during the build when the platform integrator selects to use 
#  automatic offset calculation.
