This library provides common functions to process the different guided section data. \r
+ \r
+ This library provides functions to process GUIDed sections of FFS files. Handlers may \r
+ be registered to decode GUIDed sections of FFS files. Services are provided to determine \r
+ the set of supported section GUIDs, collection information about a specific GUIDed section, \r
+ and decode a specific GUIDed section. \r
+ \r
+ A library instance that produces this library class may be used to produce a \r
+ EFI_PEI_GUIDED_SECTION_EXTRACTION_PPI or a EFI_GUIDED_SECTION_EXTRACTION_PROTOCOL \r
+ providing a simple method to extend the number of GUIDed sections types a platform supports.\r
