 Version 1.2 of the metadata format adds a number of optional fields
 designed to make third-party packaging of Python Software easier.
 These fields are "Requires-Python", "Requires-External", "Requires-Dist",
-"Provides-Dist", "Provides-Extra", and "Obsoletes-Dist".  This version also changes the
+"Provides-Dist", and "Obsoletes-Dist".  This version also changes the
 "Platform" field. Three new fields were also added: "Maintainer",
 "Maintainer-email" and "Project-URL".

-Provides-Extra (multiple use)
-:::::::::::::::::::::::::::::
-
-A string containing the name of an optional feature. Must be a valid Python
-identifier. May be used to make a dependency conditional on whether the
-optional feature has been requested.
-
-Example::
-
-    Provides-Extra: pdf
-    Requires-Dist: reportlab; extra == 'pdf'
-
-A second distribution requires an optional dependency by placing it
-inside square brackets, and can request multiple features by separating
-them with a comma (,). The requirements are evaluated for each requested
-feature and added to the set of requirements for the distribution.
-
-Example::
-
-    Requires-Dist: beaglevote[pdf]
-    Requires-Dist: libexample[test, doc]
-
-Two feature names `test` and `doc` are reserved to mark dependencies that
-are needed for running automated tests and generating documentation,
-respectively.
-
-It is legal to specify `Provides-Extra:` without referencing it in any
-`Requires-Dist:`.
