/** @file

  This file declares Boot Script Executer PPI.
 | 
						|
 | 
						|
  This PPI is published by a PEIM upon dispatch and provides an execution engine for the
 | 
						|
  Framework boot script. This PEIM should be platform neutral and have no specific knowledge of
 | 
						|
  platform instructions and other information. The ability to interpret the boot script depends on the
 | 
						|
  abundance of other PPIs that are available. For example, if the script requests an SMBus command
 | 
						|
  execution, the PEIM looks for a relevant PPI that is available to execute it, rather than executing it
 | 
						|
  by issuing the native IA-32 instruction.
