The EDK Module Structure Explained

The following three tables explain the structure of the EDK source code.

• Module Maintainers: a list of who is responsible for the module. This reponsibility includes ensuring proper management of defects, enhancements and code quality of changes to code that falls within this module.
• Directory to Module Table: this table explains the relationship between the CVS directories and the EDK Module List
• Definition to Module Table: this table explains the definition of each module
