+      This library is the reference implementation of the Python wheel packaging standard,
+      as defined in PEP 427.
+
+      It has two different roles:
+
+      - A setuptools extension for building wheels that provides the bdist_wheel setuptools command
+      - A command line tool for working with wheel files
+
+      It should be noted that wheel is not intended to be used as a library,
+      and as such there is no stable, public API.
