-EDK II Maintainers
-==================
-
-This file provides information about the primary maintainers for
-EDK II.
-
-In general, you should not privately email the maintainer. You should
-email the edk2-devel list, but you can also Cc the maintainer.
-
-Descriptions of section entries:
-
-  L: Mailing list that is relevant to this area (default is edk2-devel)
-     Patches and questions should be sent to the email list.
-  M: Cc address for patches and questions (ie, the package maintainer)
-  W: Web-page with status/info
-  T: SCM tree type and location.  Type is one of: git, svn.
-  S: Status, one of the following:
-     Supported:  Someone is actually paid to look after this.
-     Maintained: Someone actually looks after it.
-     Odd Fixes:  It has a maintainer but they don't have time to do
-                 much other than throw the odd patch in. See below.
-     Orphan:     No current maintainer [but maybe you could take the
-                 role as you write your new code].
-     Obsolete:   Old code. Something tagged obsolete generally means
-                 it has been replaced by a better system and you
-                 should be using that.
