Extract the information relevant for distutils from the package manifest.
The following keys will be set:
The "name" and "version" are taken from the eponymous tags.
A single maintainer will set the keys "maintainer" and
"maintainer_email" while multiple maintainers are merged into the
"maintainer" fields (including their emails). Authors are handled
likewise.
The first URL of type "website" (or without a type) is used for
the "url" field.
The "description" is taken from the eponymous tag if it does not
exceed 200 characters and has no newlines. If it does "description"
contains the truncated text while "long_description" contains the
complete.
All licenses are merged into the "license" field.
:param kwargs: All keyword arguments are passed through. The above
mentioned keys are verified to be identical if passed as a
keyword argument
:returns: return dict populated with parsed fields and passed
keyword arguments
